Bot luring theory in Varrock w301:
Requirements: 2+ players
Skype voice call(optional)
Method:
You trade a level <20 bot and click as fast as you can towards the mages south of varrock. Don't run too far, you want the bot to catch up with you after a few steps. Organize you and your partner(s) so that as soon as you click decline they trade the bot and run a few steps. Repeat until you are at the mages. Hopefully the bot would prioritize the trades over running back to its trading tile. This would probably work best with several people.
