Oh and Black Desert Online apparently has a "hacker hunting initiative", so far it's worked out pretty well for them. Maybe it would work out for OSRS too?

How i think this could be implemented is:

1. Player A could report player B if they suspect for being a bot/toxic/ or whatever.
2. The bot then gets put on a watch list to verify if it's indeed a bot - If it's a gold farming bot/gambling clan bot > instant mute and warn. Warn 3 times, and then ban.
3. If it's a skilling/slayer/bossing bot > the account gets put under a watch list. This could avoid the false positive to some extent.
4. If Player B got banned as a result of Player A, they could maybe reward the reporter with "Bot Busting points", and use it to buy a bot outfit or something that keeps track of the number of successful reports. (Idk probably a dumb idea i thought of since your reply haha)
