I have recently contacted blizzard support, and I got a response basically saying that deleting and re-registering for a blizzard account, and buying a new Overwatch would resolve the issue. So, no re-bans unless you use a hack on the new Overwatch account. However, they did state "according to Overwatch [Country I reside] terms", so it might be just my country. Post below your account's re-bans/no re-bans, and your country for others to see. Thanks!
