Yesterday I got my mt gox acc locked. I thought it was strange since I barely use the service and put a few hundred a month through it. I wasn't passing any limits or moving any amount of money that matters. Well today I got a reply to my support ticket, here it is.
Hello Name,
Thank you for your inquiry. Due to the incident of stolen coins from Bitcoinica a couple of weeks ago, the accounts that are suspected to have been receiving the tainted coins were flagged for AML. If you believe that this was done in error, please submit your official ID and proof of residence so that the AML team may verify your account. Our apologies for the inconvenience caused and thank you for your kind cooperation in this matter.
Thanks,
MtGox.com Team
This is the first time BTC has entered my acc since the linode hacks. It was less than $150 and it was payments from customers all over the world. So of course there might be some tainted coins in there but I suspect the percent of them would be very low. I also bet any of you that have accepted payments in the last few weeks will have the same small percent of taint. Of course Mt gox sees this is a great opportunity to shit on the community when it's down, and steal from us. It's obvious they are using this as an excuse to lock accounts based on the chance they won't verify, then profit. Nice business practices there.
Are they even allowed to do this? I'm sure their EULA says they can, right after they sacrifice your firstborn and empty your bank account because of a typo, but legally? They think they can say what coins are good or bad? How could merchants accept payments if this is the case? It's the same as a charge back just through different means.
Here you are our official answer (See Reddit) on this matter :
--------------------------------------
The word "frozen" is inadequate.
Our automatic system tracked coins we suspect stolen from another point, which means we are likely to get a request from law enforcement to identify you (only within the scope of a current and valid investigation). If we don't have your ID on file, we require one.
We are not to decide if you are allowed or not to sell the coins you deposit on MtGox. This is your own responsibility, taken on your own name. This is another reason we need to have an ID on file that matches your account in this specific case.
As soon as you submit the required documents for verification, you can do whatever you want with the funds on your account. Note that not submitting an ID doesn't mean nothing will happen. If a criminal investigation is indeed in progress, we won't be able to deny access to other identifying records such as IP address and others. This doesn't mean either we will provide private details to just any court either.
--------------------------------------
We understand your position and we even have a solution for you, so please do not hesitate to send us your AML document as soon as possible. We are sure that you are an honest person doing honest business and that the "tainted" coins arrived in your hands without you noticing they were stolen. Our goal here is not to bother you, our goal is to track down who stole these coins and make sure to help people to recover their coins and prevent others to have their coins stolen.
