While that is the case, you can get around this by using Mousekeys. I've actually set up a little machine to hit 5 on the numpad to click every few game ticks. From the game's perspective, I'm not cheating. But it is a hardware solution because a software one would be easily detected.

Also random events don't exist in Runescape 3, only Old School Runescape. The anti-bot technology implemented in RS3 doesn't seem to have been ported over to the older version of the game yet, perhaps due to it running on an older version of the game's engine.
