Some have luck, most get banned eventually. No bg bot is safe due to pathing and interaction with other players. In a BG if you run by a player in need and dont stop you get called out. To each their own though! I enjoy it, have used it, have been banned and have others who have not. Up to you.
I've been using it for around a year now. I've been banned once, but it was because I had it configured wrong (the bot stutter-stepped all night). The logic is great, and people usually see you as a really shitty player rather than a bot. Definitely worth it.
I've had great success with it. I usually end up pairing it with a premium routine and do quite well. I only sometimes afk it, because I'll run it while I'm doing other things at home. I usually rank in the top 1/3 of the bg after using a premium routine.
