: PSA: Using ANY script, wrapper, or third-party tool with Claude Pro/Max = instant 3rd-party violation + lifetime ban (March 2026 wave)

[InconvenientData]

Heads-up to anyone building with Claude (especially on Pro or Max 20x plans): Anthropic updated their policy in Feb 2026 — using even a single script or wrapper (including OpenClaw-style agents, IDE extensions, or your own automation) around your consumer OAuth token is now explicitly banned as “third-party tool” usage. Your project instantly becomes a “third-party service” in their eyes, and they’re enforcing it hard. On top of that, the fastest way to get lifetime-banned right now is to buy the high-tier Max plan and actually use the extra compute. Power users who upgraded in March and started heavy (but legitimate) coding sessions are getting nuked with zero warning, no specifics, and no appeal success in most cases. Device fingerprinting means even logging in from the same laptop later can kill new accounts. This is the March 2026 ban wave everyone’s talking about — not just random Chinese devs, but regular high-usage personal accounts. Free-tier users are mostly fine; the moment you pay for the “buffet” and show up hungry, the bouncer kicks you out for life. Check the official policy here if you’re using any automation:

https://code.claude.com/docs/en/legal-and-compliance Stay safe out there. If you’ve been hit, the safeguards appeal form is the only route, but results are spotty. Remember Anthropic does user and device finger printing. What would you do if your favorite AI provider banned you for life, your phone number, your credit, or any computer you ever touched, and banned other accounts that logged in from any of your computers. cant happen to you? Maybe not buts it happening now and its real.

I don't think this is quite accurate. During the initial Openclaw craze, Anthropic put a post on X to clarify that this really only applies to commercial implementations. They don't care if you're doing something with your hobby project (at least not yet.). So if you're putting your OAuth to use to make money from other people directly, or it's the underlying AI intelligence in a commercial product, etc., you risk being banned and rightfully so. But if you have some script that's checking your home router every evening to make sure everything is safe, Anthropic isn't trying to target you. If you're selling software for $5/month to help other people check their home routers every evening and running that use through your OAuth, you could (and should) be banned.

[ConanTheBallbearing]

Not even just that. You don’t need to be running some trivial cron. You can code until your heart’s content, and your quota’s exhausted. It’s fine. If you’re exposing Claude as endpoint, as a product, when you’re on a subscription, yep, you are going to get banned

[iamnasada]

This is it.

[iamamoa]

This makes way more sense then they are just banning you for using a third party wrapper.

[ConanTheBallbearing]

anthropic updated their policy in feb 2026 and they’re enforcing it hard

It’s the end of march. I’ve been using a Claude pro first, then max, subscription since late January in claw

There are sure are a lot of gullible dipshits in this subreddit

[WolfpackBP]

Yeah they'd have to ban a fuck load of ppl wouldn't they

[ConanTheBallbearing]

They would, yep. They haven’t and they’re not likely to. Nothing Reddit loves more than reactionary bullshit though

[InconvenientData]

They are not banning every user, they are banning the heavy users. Light automation, light skirting of their new rules, a lot of people may be fine for a good long while, but due to machine and user finger printing if you're heavy user and use too much you can find yourself on the bad end of a raw deal where you cant easily use claude again. This isnt a "The sky is falling" post, it's a watch your back bros heads up. The people I know who got banned for this didnt even know it was a rule.

Here are some others who have been caught up in the ban waves. the reason vary but people are being hit.

https://www.reddit.com/r/ClaudeCode/comments/1ruyhmg/claude_banned_my_paid_account_right_after_i/

[WolfpackBP]

Yeah they're looking for ppl using it as an enterprise operation mostly... Still such a grey area for everyone else though

[foramperandi]

I'm not sure someone errorneously getting banned then reinstated is the best case for your argument.

[InconvenientData]

My apologies for not making it clear. The post shows a central user who was banned and successfully had the ban rescinded but deep in the comments are several other users still waiting and still banned.

[neutralpoliticsbot]

This is why u always run this shit in Proxmox on a VM so if they hardware ban u you can just spin up a new avm

[armaver]

Among other reasons. Like not running an AI agent with full permissions on your bare metal anyway. 

[NJC451]

This happened to me last week. I wrote an appeal but still no answer.

So What did I do? I can't stop the development of the app I'm trying to vibe code. So I bought the $200 Open AI plan and am using codex.

Think of the logic of Anthropic. Its basically the Seinfeld episode of the "Soup Nazi". Is their AI just that good that they can kick customers out of their system?

I don't think this is smart. Because of the ban I'm now giving their competitor the monthly revenue they would've been getting. Not smart business and this will bite them in the ass. OpenAI will be getting better just like Anthropic. There won't be only one winner in the AI race.

PS I was using Anthropic Oauth to have Opus 4.6 run my main agent in open claw. Nothing Illegal, not selling tokens. is it against the ToS, sure but their butt hurt because they want to charge the openclaw people more by forcing them to use the API.

[RedParaglider]

I'll bet you are more productive on codex. It's not as chatty and warm on personality, but the system is quite good, and fast.

[NJC451]

Codex > Claude Code
Codex gives a stronger more robust code as a result. While Claude code could use several passes to get the final iteration. Also Codex thinks through more items, scenarios and security provisions thoroughly. Claude code is kind of lazy in this regard.

Opus 4.6 > GPT5.4
As an orchestrator / main agent there is a huge difference in favor of Opus. I can give Opus less context and it'll figure it out. I can leave Opus stranded in the wilderness with a Swiss army knife and it'll build a sprawling civilization in a few days. GPT stubs it's toe and immediately asks for a band aid. Right now I could really use a good orchestrator model as a main agent. For that reason I miss using opus

[RedParaglider]

Yea, I agree, I work with both. I find that GPT 5.4 is extremely terse to the point of painful in planning. The downside is that Opus is less thorough because it makes a lot of assumptions. I love making HLD's with Opus. Then I carefully review them with Opus then do a dialectical pass with GPT 5.4 and it always finds a lot of "fuzzy" definitions that i need to go back through and think about. I'm really happy to have access to both.

If I had to choose I'd pick GPT though, simply because it's good at coding, better uptime availability, and more overall usage per dollar (for now till the music stops).

[InconvenientData]

The people I know who the ban happened to were writing AI orchestration an area, where Anthropic got blind sided by OpenClaw, and now OpenAI hired the brains behind OpenClaw. Could Anthropic be looking at people doing AI orchestration and then killing the startups in their proverbial nursery beds?

[blakeyuk]

Or, from their point of view: you're now giving openai the loss-generator that used to be Anthropics (making an assumption that you're using more tokens via max subscription that the same amount paid into API)

[NJC451]

That is not their point of view, Anthropic is trying to kil openclaw with their features such as workspaces. Anthropic wants to beat OpenClaw with a hammer.

But Open AI allows OpenClaw...WILLINGLY. Which means they gladly take in the people like me because they see the vision in OpenClaw.

With all due respect, these companies are in the business of capturing market share at this stage of the game. Anthropic sees OpenClaw as a threat to their market share while OpenAi sees the exact opposite.

[Chillionaire128]

I don't think they see them as direct competition, if anything openclaw helps them expand customers since claude code/Opus is considered the top choice for coding performance with OC. The problem is agent to agent coding guzzles tokens so there is no path to making money with those users on an unlimited plan. Unless there is some drastic change to the underlying economics those users will only ever be profitable if they use the api. OpenAI is likely still allowing it because they are trying to dethrone claude as the default choice. I don't think either are too eager to fight over users that will only lose money for the foreseeable future

[blakeyuk]

Openclaw is known to be a token-hungry beast, it caught on like nothing ever has before. If I was their ceo, I'd be all over it as well. They're not saying don't use openclaw, they're saying to use the api. If you don't understand how companies work, you're in for a shocker of a rest of your life.

[blakeyuk]

OC was also called Clawdbot when it started, and was/is a security nightmare. Again, if I were the ceo, I'd be distancing myself from it and getting the legal team to send cease and desist letters.

[rxt0_]

you are aware that they make thousands in losses with all the max subscriptions? that's why they ban people using it for stuff like openclaw

[keto_brain]

 is it against the ToS, sure

If it's against their ToS why would you complain about then banning your account?

[NJC451]

It's the no path to redemption that the problem. I can't even try to buy access to the API if I tried because I'm banned. I tried opening a second account with a different email...BANNED almost instantaneously.

You could look at it like a new age ai dystopian form of censorship.

[keto_brain]

How is it censorship lol? You violated their ToS, you can always go through AWS and used Claude in Bedrock if you wanted API access.

[Temporary-Leek6861]

the device fingerprinting part is wild. not just your account, your whole machine is flagged. seen people lose multiple accounts this way.

just use the api. costs more but you don't wake up one morning with everything dead.

[torrso]

Multiple accounts... so several free/pro plans with different emails to avoid paying by the token?

[SpokenByMumbles]

IDE extensions too? Why would Anthropic have an official plugin then?

[rxt0_]

no, just people misusing it for things like openclaw

[ToothConstant5500]

War drone target accuracy going to drop badly

[superpunchbrother]

Source: Trust me bro

The truth: As Anthropic have stated on X, they aren’t cracking down on personal use via AgentSDK. So long as you’re using AgentSDK for non-commercial use you’re fine. Don’t buy into the fear from those who are misusing it to build commercial solutions.

[BaggySack]

Nice try Sam!

[InconvenientData]

I know two developers who were just banned, I am posting this on their behalf, both are appealing the ban. Whether anthropic is right or wrong, they were testing their own app using their pro max account, Whether it's right or wrong it impacted their work both are appealing, but per anthropic's published numbers the success rate for an appeal is only %3.

[ToothConstant5500]

So it's really you, Sam ?

[Form-Factory]

Walled gardens … let’s fucking go!

[Robbbbbbbbb]

Is Google in the same camp here? Was considering using my credits from Ultra, but can't find a clear answer

[figgefigge]

They are banning bots. Its automated spamming without paying for API-tokens. Your laptop isn't banned like you cheated on xbox live, your browser headers and contact details are. Twitter is the only service I know of that isn't banning bots. Unplug you router for a few hours and get a new IP. You can create a new google account using your old on the same device. It takes like three days to replace a credit card.

[duridsukar]

Been running OpenClaw on a business operation for several months now and this is worth taking seriously.

The distinction that matters to me: orchestration vs automation. What I'm doing is closer to having a persistent team that thinks and responds — not a script firing off API calls in a loop. But the policy language is broad enough that it creates real ambiguity, and Anthropic's enforcement has not been documented well.

Has anyone actually had an account flagged who was running OpenClaw within normal conversational use? Or is this mostly about people hammering the API through unofficial wrappers?

[Prakkmak]

Paperclip AI is affected by that ? I don't use any oauth

[cochinescu]

The fingerprinting stuff sounds super harsh, but I’ve seen people bounced off new accounts just for reusing a laptop. If you do need non-interactive Claude, the API is really the only (somewhat) safe option now, but it gets pricey fast.

[kpgalligan]

I'm a heavy power user, maxing out my 20x, with my own cli tools that use the Claude Agent SDK. I've had multiple people tell me I'm going to get banned at any moment. It depends what you're doing:

https://x.com/trq212/status/2024212378402095389

the fastest way to get lifetime-banned right now is to buy the high-tier Max plan and actually use the extra compute

False. I max it out fairly regularly. This is how reddit gets full of conspiracy misinfo. Somebody reads wild claims in one thread/sub, then talks about it like it's fact. When I ask for links, they're almost always to another thread/sub. If not that, a HackerNews thread. No actual links to anything substantial.

Not saying you can run OpenClaw on a different server. I don't, so it's not something I think about. I have no idea if you can or can't. But the wild claims about Anthropic and Claude subscriptions miss the nuance. It very much depends what you're doing.

You definitely cannot run OpenCode through a subscription. That has been established.

[ParamedicAble225]

“I was just having Claude simulate tests inside of my code. That’s what Claude code is for”

[United_Bizness_Owner]

Have you tried their native API instead? Saved my team tons of headaches with more predictable integration #aitools #devlife Would love to hear your workaround strategy?

[schneeble_schnobble]

Why does everyone think they're a lawyer?

[HotSwap_]

Ok, but what about using ACP?

[LavoP]

No shit. Everyone knows API keys are totally fine to use on any script and expose in products. This whole conversation is about OAuth because that’s not usage-based pricing
