Ty guys for all your infos, i think same of you...
I've botted not more than 8 hours/day (4h + 2h stop + 4h), every 3 days i did some raid/dungeon by hand, and i never bought RAF gametime (only legit 60days gamecard)... So i did my best for get the bot more "human like" possible, i got only some reports for botting... So i think that check from Blizzard are totally random, maybe after a report from someone.
I will bot 24/7 now until new ban, then i restart again...
No sense to stress my mind with pause, play by hand, be care from reports etc. if you will be banned anyway. Get the most from botting will be my style now
