We do not allow it for a number of reasons, but the main reason is because Treyarch has a proper method of handling cheaters and people that are suspected of cheating. Report them in-game. If you want to take it further then report them to Sony also.
We've asked you not to do this. Contesting our rules publicly is something we anticipate, but you should really message us for a better one on one discussion. Attempting to crowdsource a change in policy will not happen either if that was your angle. That said, don't PM me about it. I'm not going to reiterate why since this is being handled publicly.
