Anti-bot software is not the way to go. All anti-cheat programs are very easy to bypass, including Warden, PunkBuster, Hackshield, etc. I know this because I used to write hacks/bypasses for several online games for various online companies. Now, I doubt Jagex's anti-cheat could come up with anything remotely close to that of WoW, Battlefield, and many more. Not all bots use the coordinate system or even object IDs; Mainly those that are not written in Java. It is still quite simple to retrieve/send the information/location without use of these things. If Jagex did drastically change their game to use different methods, it would simply force the bot makers to change theirs... Which I highly doubt would take long (Since, as I said, some bots are already being developed that don't even use that system ;)). And then once they did, we're back at square one. Now, as to why the bots crash after updates, I'm not sure because I haven't used Java in an extremely long time. I don't know why the bot developers don't simply have their bots automatically update after each game update. Hell, once we wrote a hack, if there was a game update it updated itself... But then again different languages = different capabilities I guess. I don't assume it would be too hard. This.
