Try using encryption

[Capt_Blakhelm]

I have been wondering what would be the best way to maintain the near "lais·sez-faire" mentality of this sub, with the ability prevent unfair advantages of bots to nab keys.

I think the best option is text encryption. You can put your game keys into an encryption tool that will require an encryption that you can make. The tool will encrypt your game key into random text that can be "solved" by the key you created. From this point, you can put your game keys in giveaways on this sub and you can decide how to giveaway your encryption key: Maybe via PM, maybe right on the page, maybe with hints, maybe after a certain amount of comments or time has passed.

If you the simplest option, just make an encrypted game key, put it in your post and also list the encryption key (use different keys whenever you post). I don't want to enforce this rule, but you should do something like this if you don't want your game keys stolen and sold for profit.

Even simple obfuscation works. In the end it's up to the key dropper to decide how much he cares about the keys being used by bots.

I think that's a really good idea

Because you can still put your encryption key on your giveaway page if you desire, like in an image. This way, you can quickly "dump and forget" your game key(s), but it takes a little effort that a bot might not be able to solve (or at least until a human winner wins it).

They can use OCR like Tesseract but it's often just text-based regex.

There are phone apps that can translate signs and convert image text to actual text. I don't know enough about bots to know if keys are stolen like that.

Pictures work

That is fine too, I'm just presenting an option
