What usually happens when you're detected with a hack, is some sort of temp flag is set, and is usually reset after reboot(that's how it worked with GG I believe). So if you login to an account, a get banned, you're probably safe rebooting your computer, but idk how long these flags can be set for, so it may not be. I don't play any games really, so I wouldn't know, I've never been banned.
