I botted 2 void sets in a week and a third one right before bonus xp (novice boat) and still havent gotten banned.
You could try conquest minigame multi log in and let your self win.
It takes like 15+ hours in novice, 10 hours in veteran, and 7 hours if you join a 110+ clan or somethnig.
Pest control has a HIGH ban rate. I would recommend doing it legit as the org. world for pc is SHIT points/h due to the bots. Join soulfire or something, their on rs forums, 100+ points per hour easy, but 110+ cb.
