Is this safe? What's the chances of getting banned from using this?
Only use this hack on cracked versions of black ops (nemexisOps).
If you want to hack on nemexisOps I would advice you to use this hack: https://www.mpgh.net/forum/245-call-d...s-wm-hack.html, the NemexisOps WM Hack is very safe since NemexisOps doesn't have any anti-cheat. And it allows you to change your name and userID so even cheat-reports don't work.
