There totally no save method to BOT - grinding, questing, BG or whatever - everything "can" get you banned.
sure but is it very likely to get banned with 100% grindbot 85-90? actually Iam using mixedmode AV (bg) + grindbot. it should be saver I guess....
I like grindbot best. Grind spots are almost always empty and you don't get the WoW bugs that you get with quest NPCs.
