Just use the many free bots out there.
Or buy scripts for some of the well known working bots.
I doubt anyone with a private bot would just go around selling it to random people.
For some reason I am unable to move this thread, so I am just going to close it.
Feel free to repost, but please post in the scripts section instead of RuneScape 2 Cheating. If you have any question about where that is, feel free to PM me
