Is any modding even slightly safe?

u just use it 1 game and then u quit the lobby , go to baracks... so even if some1 wanna report you he wont click on your name and report so fast=>he wont even search for u after. but there is a really low chance to report you for boost unless you play with the trainer and make all prestiges with 1000 kills

People wont notice it unless you go to max prestiege or something, but it does not really matter. Treyarch most likely has systems in place to detect when someone has unusually ranked up. Your best bet if you dont want to be banned, is not use it. But if you like being banned. go ahead

You won't be banned automatically because it is currently undetected by VAC.

However, it's very easy to detect manually. If someone looks at the amount of kills / games won you have and compares that to the level you are, it is easy to tell if you cheated.

Bottom line is you will not get banned as long as you don't get reported. Unless someone is out to get you specifically, I doubt anybody will notice.

You can mod, just don't do it that people can see it. You will get a Perm-ban
