I never found Aimbots to be a problem. I noticed it some back in BF2142 along with some exploiting bugs and a few wallhacks in early BF3 but I haven't seen it at all lately. There really is not much incentive to be a headshot king anyway other than some weapon addon's. It's not Unreal Tourny or nothing, though i'm sure some kids get off on it. From what I understand, an actual working Aimbot is as much of a pain to get and sustainable as direct tv hack cards if you don't get banned from servers, the others are malware infested or fakes to get you to take surveys and do certain offers, makes sense since i'm sure it's a popular search term. Plus the lack of incentive to actually have one, I mean wow a lousy 100 points and some mostly crappy addon's. woot. I can get over 10k points just by helping team mates and capturing bases faster than the snipers just sitting there plunking. I'd be suprised if very many even bother which has to get boring quick i'd imagine, but again I haven't seen it at all since i picked the game back up a couople months ago.
I guess my stats were not reset. It was earlier today, I was private first class but now it's restored. wierd.
