I believe that bans are mainly issued based on player reports. I've used this hack on and off in the past couple of days, and have not been banned for it. Make sure you limit the no-recoil hack to weapons that don't have too much noticeable recoil, for example, the M37 or SCAR-H. You should be fine from there. I've also found that setting my mouse sensitivity to a higher setting than I'm used to also helps to create a pseudo-recoil impression, especially in the kill cams. However, the main thing to worry about is to not use it on high recoil guns, LMGs, snipers, rockets, etc.
the only person that can ban you, is the big chief mr battleye himself. no admin or hacker or player can do this. In addition to this the big chief mr battleye will ban you based on the bypasser you're using NOT what scripts you are using.
