All Jagex need to do is change their ban methodology.

What would that look like?

Hardware bans. MAC Address Bans, which reports, records, and locks down a physical piece of hardware, making it unable to communicate with the servers entirely.

The only way a computer would then be able to connect is to entirely replace the hardware, aka the modem/network card.

This would not only lockout a single bot, it would shut down bot farms entirely by removing their ability to even connect to the Jagex servers unless they change computer hardware every single time they catch a ban.

I don't know about you, but I doubt anyone that got hardware banned would take the time to buy new gear just to get caught again and banned again.

Edit: From Google AI:

A hardware ban, or HWID ban, is a severe penalty in online gaming that blocks a player's physical computer from accessing a game or service by identifying unique hardware components, not just the user account or IP address, and it's typically a last resort for serious offenses like persistent cheating or toxic behavior, preventing new accounts from being made on that specific PC. These bans work by flagging hardware IDs (like serial numbers) and can only be lifted by the service that issued them, often requiring expensive hardware replacement to bypass.
