like the subject. Do I need to modify my ip address and something like that. Coz I worries about that blizzard would track my ip
There are more ways than IP to track people, such as hardware ID. I take it some of your accounts were irrevocably banned? Tbh, I'd be tempted to get a vanilla acc and bot it with quest bot fairly hard to 60, and see if they were hot on my heels enough to ban me again or not.
