Please understand that no cheats are "safe" and you can be banned fast using them, however, you can prevent that or lower your chances of being banned by playing "half-legit" means that you can use the aimbot only when necessary, no-recoil when necessary and so on. The ban however cannot be bypassed and if you're being HWID banned you either need a spoofer or reinstall your windows.
I'm afraid there is nothing you can do. You can create a new account and try not to enable all the hack functions unless necessary, try to play legit also
