Got my paladin 55 banned today for botting, i should have picked a better spot for it i guess. I'm pretty sure nearby gankers spotted me in EPL and reported it.
Personally i don't think the chances of getting banned single botting is high. Only reason for you to get banned would be if someone reported you.
@excell003 Totally agree, it's so easy to spot. All these unusual patterns and pathings. Like the insta 180 turn.
