how did they break the bots? I made a very basic runescape autoclicker at https://www.garyshood.com/rsclient/ I wonder if it gets banned in game now.
But I think your auto-typer was really one of the only "allowed" 3rd party programs, and auto-clicking was never really enforced strictly.
When the bots got advanced, they pretty much had two methods via either injection or emulation of the entire game. So either they broke them through making a bunch of fundamental changes of ingame systems or the ability to connect to the servers.
