I lost 3 acc to the ban wave, but guess most of us did. But since from the fix zero ban or warning from blizz.
Zero guild lost, only items that were on banned acc.
Dont mask my IP. Just have a relogger that logs out every 2-3 hours for 10-15mins. Turn them off when I sleep 5-7 hours.
I would always add one at the time. Make him 100%, as checking if he is getting stuck or acting like a bot.
If take the time to master the setup, you will reduce the risk of getting banned.
