I got PB banned for 2 minutes even though I have not injected it.
Another scenario was that I entered a server successfully, and when I inject it, i got kicked immediately.
I have not even used aimbot even once when I got the hack injected, however got kicked due to aimbot.
So I conclude it is detected.
The cheat can't be protected from retards.. and I am sad saying this People will loose the ability to play multiplayer because they don't understand that if they use the cheat on pb servers or more generally on every server(because of user stats) too obvious will get banned, that the admins are not retard they can understand that a player is cheating, even if the cheat will never get detected by software. . .
