You must make the distinction between ATTEMPTED hacking, an actual in-game hack and a cheat.
So far as I know, there is no in-game hacking in AH or WB, even though, as HS said, there are a lot of attempted hacks. HTC will not say anything about it, I bet, but I am sure they have the same problem with attempts, if not more than WB because of the 2 week trial. Who cares, they don't get in, so it is a moot point on attempted hacks.
In-game cheats are there, in any game, it is a matter of the community policing itself, as this one and the WB community do so well, the occasional witch hunt not withstanding.
