I use AB on my main because I don't quite care![]()
It's like saying: i throw money out of the window.. i don't care... but hey it's your money.

And It was like 1week since I last use the bot
It's your specific case.. but reading the forums, the wave ban who happened yesterday was massive, and not just because of AH scripts, so you may be banned because of this reason, but a lot of people didn't used the AH at all, so I guess AB was detected on login someway.
