I came back to WoW after taking a break and I have been using the bot for almost a month now. I have botted everyday but never more than 16 hours straight. I have leveled 3 characters from 90-100 in that time. I am generally botting my garrison on 7 characters as well as all of the apexis objectives and dailies in Tanaan. I have yet to receive a ban.
I am neither expecting to get banned nor do I think I am 100% safe from a ban.
