To be fair, when a character does get hacked in WoW, blizz has top notch customer service in handling it.
Friend (you know him, Trinsie) got his account hacked, and they npced all his shit, took everything out of the guildbank and npced that, then took all the gold. He got all his stuff back in two weeks, as well as they sent the guild leader everything that was taken from the bank.
I don't think you can prevent it 100%, but you can do excellent customer service, so when it does happen, it's a non-issue.
