So if I got banned on my laptop but have a desktop, can I but a new copy and play on my desktop? How does it all work?
Oh yes absolutely not doing that lol what about IP? Should I change that prior to getting another copy on a new PC?
HWID means Hardware ID so it identifies all the hardware components in your PC or in your case your laptop and gives it a unique identification number which could be blocked by blizzard. Nobody is sure now if blizzard is using HWID bans or just ban your account.
See I've heard/read that people have bought new copies on new accounts and gotten immediately banned.
