made a new account just to check if there is an auto-detect systeem, lvl 20+ on a well known questing profile. But seems fine so far.
But once you have been detected.. and if you are so lucky to get unsuspended... it seems they manually keep an eye on you. Previous account got banned at lvl 26 (probably reported), got it back, manually lvld to 32.. turned the bot on for a couple hours while watching and encountered no other players.... banned again.
Will post here if the botting account get's banned.
