Account ban for now. This may change in the future as ow2 is free to play. who knows, up to blizzard to decide what to doQuote:
What happens when you get banned? is it an account ban or hwid ban? Can you just buy a new account and play?
You can just make new account with another verified sms on 5sim for 3-20 cents/number and play, remind this is a free to play game, so hwid ban may coming soon
