What if this actually happened though?
Is the Anti Cheat team expected to see it was suddenly a different IP address during their investigation and then suspect they might've been hacked? But now that I think about it, this could be mimicked by simply using a VPN I guess. Sadge.
Sadly these things can happen for real, it is the sad truth. Any large company will straight forwardly tell you that the security of your account is your own responsibility.
