Got banned in like 3 alts i used to play, but it was my fault, used one script in particular (hanbot) that is not safe and its 100% detected, used in my main like 3 times and luckyly had time to stop using it on it before i got banned on it too, so i would say you could expect always a ban, and the most safe option is scripting only in alts and smurfs, never om mains.
