I'm not sure whether we should file this under "I'm glad Blizzard doesn't do this" or "I wish Blizzard would do this!" but Chinese gaming company Moliyo (who run the MMO Cabal Online) is offering banned players an interesting method by which to reactivate their accounts. What do you have to do? Simple! Donate blood, and they'll unlock your banned account within three days. And if you're an active player, you can receive a special game account for participating.
This is, to my knowledge, a completely unique way of going about reinstating banned players -- while supporting a good cause. And asking players to donate blood is no more time-consuming than Blizzard's usual procedure for restoring stolen accounts, which requires notarized documentation proving your identity. (And will still likely take several weeks for Blizzard to investigate and restore any missing property, which doesn't always happen.) Perhaps Moliyo's way is easier in the long run -- though, being a needle-phobic, I'll stick to the usual customer service queues.
