It worked fine till my account was permanently ban 

Just because the cheat is safe does not mean that a ban is impossible. Enough reports will get you a manual ban and nothing can be done about it.

Did you rage hack or just simply was too obvious??

It can be a manual ban, because the cheat is still undetected?? 

The cheat is undetected.

Thats what i said?

Unfortunately most hackers that gets banned are banned due to their own playstyle. Sometimes one gets to comfortable with the cheat and you dont notice that you are tracing, prefiring or even only shooting headshots. Rarely does the cheat or loader become "detected". If that happens the floodgates would break as the ban reports roll in. We all accept the risk of being banned, else you would not be here, but take a close look at your playstyle, you might want to tweak that a little bit!

Good luck and happy cheating!

If you were rage hacking you will get banned even if the cheat is undetected even if your playing legit and using ESP and looking through walls thats enough evidence to get you banned i'd suggest pick cheats for the games you are decent at and remember a cheaters first rule is not caring about getting banned :) 

Even though it is a boring subject, it is important to give more details about the ban. If you used it in a very obvious way or made it look legit.

This is important for the team to continue improving the programs offered here. Remembering that this section is intended for review's and it is interesting to have more information.

Anyway, head up and move on.

A noob cheater.so you think the cheat is undetected and think you can rage in the game? cheat is safe it depends on how you use it, you are banned because you rage
