Many of the multiplayer first-person shooters have cheaters. All you can do is report them in-game, if that option is available. Seems to be a fact of life with these games, and it's up to the developers to write their games in such a way that cheats won't work.

SCE wouldn't have any control of issuing a ban of the cheaters. Danger Close (and EA) would the ones who to go to.
Here is the official forum for MOH: Warfighter. I'm guessing that's the one you're talking about...
I can't find a thread to see how they deal with online cheaters, but I know DICE/EA did not tolerate cheaters/hackers one bit. It may be different for that game though.
