When Blizzard said that they will be coming down hard on cheaters in the game Overwatch, they really meant it.
Blizzard made it clear that they will not tolerate any form of cheating and that if they do find out that you are cheating, you will be ban from the game. People did not really take the threat seriously as they assume that they can get back in after purchasing a new game but it looks like that is the case.
Some cheaters have already reported that they were ban once more even after they wipe their hard drive, purchase and install the game again. Based on what the players are saying, it looks like the only way you might be able to get back in is to remove all hacking tools, uninstall Bttle.net, reinstall, created a new account, buy the game again, install the game and try again.
Is cheating really worth it if that is what you have to do to get back in?
