The PvP community, at least among those serious about being good at it, tends to be self-policing. Shunned is a strong word, but cheaters in whatever form tend to get dumped on pretty hard. Whether it's logging, exploits (like using fighters to deliberately create lag), using premium ammo in organized events, or straight up hacking. People don't tend to forget that sort of thing.
Accusations of actual hacking are pretty rare, and many have come from the uninitiated in the past. In reality it is often a skill disparity. Even with the best build, you could be dead against the best pilots in just a few minutes-- and this comes from an Xbox guy, where I have been the one dead in those few minutes, in total absence of hacks.
Now when you get a handful of the top guys noticing something fishy, that's when it's really worth looking into.
