Well so far I can play on another account on the same PC. Also another guy from this forum talked to the blizzard support and they said there are no HWID bans.
HWID bans are very uncommon in games because as a business standpoint you are potentially losing money. They might do it but I doubt.
Change HDD Serial Number , Sytem UUID , M/B SN and MAC and probably UEFI? - Since its easy to change there are enough programms for that shit. Problem is People who had use cheats got banned also if they where legit after it. So its probalby the Battlenet client ? Since it can trace your Real IP.
has anyone here been banned on their second accounts? I want to play full legit with friends now, but superafraid to get banned immediately.
