I am having a similar problem with Bitstamp. I was always wary of these exchanges and tended to stay away from them. After researching Bitstamp, I decided to give it a try. Buying and selling bitcoins was easy, the website loaded fast and support verified my account quite quickly. My first withdrawal for dollars(4digits), was processed quickly and I had funds within 5 days(international). So I decided to try a bit larger amount on March 16th. and support has messaged me with those exact questions. I answered all of them honestly, but they asked for some type of supporting financial document? I have never been asked for this by any traditional brokerage, nor bank. I am sure they are just trying to play it safe, but Mt. Gox also used a facade of AML/KYC compliance as an illusion to portray legitimacy. I have also asked them under what financial supervisory board/agency are they currently regulated under in UK or EU to collect this type of information. They said it was "internal procedures." I am a verified user with Bitstamp having both my passport and a copy of my bank statement, which I have used to withdraw.
My last contact with bitstamp support has been about 24hrs. I am sure they will take care of this as these small shops are usually swarmed with support requests. I have asked bitstamp to cancel my request, so I can simply withdraw via BTC and close my account. I am simply not going to put up with this type of nonsense out of a company that is not registered with any regulatory agency, yet is pretending to be at the forefront of regulation. We've seen this before.
I think what is most disturbing about these exchanges is how quick they are to accept deposits, but when it comes to withdraw suddenly there are all sorts of "compliance." Yet, no laws are ever cited by them. Why do they not ask this questionnaire during the account opening procedure? That is standard practice at most legitimate financial institutions when opening accounts.
Does bitstamp have anyone on this forum to PM to speed things up?
Yep. There is no good reason for any of this. Never come across it before with any kind of online account I have ever held. They have my passport scan, proof of home address and the bank account I am paying out to is the same one I have paid thousands in from. There should be no problems with this but it seems that with Bitstamp, there is for some reason.
