its xenobot. Use windbot and you won't get deleted in the beginning
i had the same, it is not ip related 100% sure
I lvled up 20 chars from lvl 1 to 8-30. They all got deleted on the same day though. Then i started to lvl up 20 chars with windbot, and they are now all level 80 botting them all at the same time always so 20 clients, and i didnt get deleted
as i mentioned in a previous post xenobot is really good to use if you are warring, pking etc. But sadly enough the cavebot side of xenobot seems to be detectable.
Also if you didn't do it yet: Try to use randomized e-mails, account numbers and password. You might get deleted on all of your accounts at once if you use like the same e-mail adres, or the same password
