I have had my account suspended before because of some of the same cc issue's. They requested my ID to confirm my identity and only because I like to tip, I went ahead and sent in the requested information because they do not require it. They said they just wanted to make sure the person using the account was the same person using the card at least on my end of things. However I do know this is one of the fastest ways to get an account due to card issues etc unbanned faster because they have the identity firm in hand and they really have no reason to dispute your identity any further, I do know some people who use vpn's on mfc as well and have tried to purchase tokens without turning their vpn off first...this is a big no no, their system automatically detects that it wasn't from the same IP that you signed up on and the system automatically freezes the account, so if any of you out there are using vpns on mfc, remember to turn it off before you buy tokens, otherwise it will freeze it and you will have to go through a bunch of stuff with support to have your account unfrozen, confirming identity etc, I only mention this to be helpful to those that use a vpn. I personally do not use one on MFC in particular.
