REALID, the dumbest thing ever

The monthly fee is paid with credit card

I highly doubt that Blizzard would ask to see your passport/visa just for to verify your name on some internet message board.

I'm not saying they would request that for the purpose of confirming you for the forums. I'm just suggesting they might one day ask you about confirming your account details. Some people would think twice about faking their name, as they couldn't confirm their ownership in case Blizzard asks for it. They sometimes to do this for several reasons: payment issues (change of card, bank rejecting the payment) or account suspicions (e.g borrowed/bought/gifted account) and so on. The chances are slim I guess, but considering the amount of time people invest in these accounts they're probably not comfortable using a fake name.
