I would still like to understand your policy related to when you call the police on your customers. The OP seems to make it sound like you need proof, but to me in the explanation it sounds like you jut need to suspect it.
As you said I was not involved in money laundering and I am glad you no longer suspect it. Sending you my marriage certificate and a bunch of other personal stuff convinced you. However what do I need to do to get you to give me information about this for all I know ongoing terrorist/money laundering watch list investigation? I have had no response from Mt. Gox and I am to the point where I am ready to get lawyers involved.
I believe it has already been made clear and that you understand the situation. But here it is again for you to read. Also please understand that I cannot give all the details on what have been done here on this forum since we would like to keep your personal information as private as possible.
1) We can't explain all the details on how do we "Flag" people or how our process work. If we do so publicly we will then offer a unique opportunity for "Bad" elements to bypass or security. So I am sorry but you will never have a clear answer on how our security features works on this matter. Please understand we are doing so in order to protect people assets including yours and our system integrity.
2) What you did is a text book case of money laundering for us based in Japan (Remember we are in Japan). I am not saying you were trying to do something bad, and you have been cleared for this. But Check all Best Practice on this matter and you will see immediately what went wrong. To give you an example, I am French, Living in Japan I own an account in France and Japan with Visa Cards attached to them. Every single time I am sending money from France to Japan, the Japanese Bank call me to check WHY ON EARTH I am sending money to myself? They won't clear the transfer if I won't give them the reasons. Things are even more complicated when I receive money from other people or companies. So in your case you can understand that some flagged has been raised.
3) What you did is against our TOS, TOS that you agreed upon. TOS that has been written by our Law Firm in compliance with Japanese Law.
4) You refused to comply with basic AML/KYC. Sorry but it is how things work, once again what you did is text book case for basic money laundering and we have strict instructions on this matter and are ask by our bank to follow them if we want to use their service. Being reluctant to submit "Proof" and proper documentations did not help your case and increased potential problems with our Bank and Japanese authorities.
5) Not being capable to verify your identity and the clear connection with the person whom you wanted to send the fund give us no other choice to report this matter to the police here in Japan. We are not the law and only the Law can decide what can be done until things are cleared. Also failing to report any suspicious activity to Japanese Law can put us in trouble and ultimately force us to stop our activity temporarily or indefinitely.
Without much solutions in our hands and your continuous refusal we had to move forward. As for today you gave us all necessary documentation and "proof" to clear your name on this matter and the case is closed. The Japanese Police has no involvement in this matter at this point.
Conclusion:
1) You do not have to worry for this matter as far as Mt.Gox is concerned.
2) You do not have to worry about the Japanese Police for this matter. Case Cleared and Close.
3) We cannot communicate any information regarding pending case, ongoing case, past case unless we are requested by law to do so. Failing to this basic duty will be heavily sanctioned here in Japan.
4) We cannot give you the details on how things works when it comes to Money Laundering for example since it will help "Bad" elements to by pass our security measures.
I sincerely hope that this post will put an end to this matter and clear your mind.
Regards
