. If stating that fact sounds like 'whining' to you than I would question your neutrality in the matter.
They are asking for a photo ID so that you can confirm that you truly are the individual who owns the Dwolla account.
You are refusing to give that to them, with the excuse that you can't trust them with that very valuable piece of information.
Fine. But that was their policy for Dwolla since May 25th. And when you signed up with Mt. Gox you agreed to the terms of service, which say:
Transactions may be frozen until the identity check has been considered satisfactory by Mt. Gox as required by applicable money laundering laws.
I''m sorry that Mt. Gox is doing a shitty thing (requiring photo ID for all accounts that use Dwolla). But whining (yes, after the first time, it now is considered whining) here on the forum isn't going to get you your $100 back.
Sending in your photo ID will get you your $100 back. If you choose to not send in your photo id, you are free to do so, just that doing so will cause you to not get your $100 back. It will eventually (years ?) be turned over to the authorities in Japan as abandoned property.
