On your website Sushi-GB is *was* posted as your skype contact. I found your website first before I found your BTCtalk thread, if you set up a store front poorly because you expect all traffic to come prepped from this forum and no one will stumble apon it, you are going to have issues. I tried contacting you at your posted address but there was no such account. Someone else likely made the same discovery and has decided to use it for evil. Why would your website contain false information? I don't believe it was malicious in anyway on your end, but it certainly allowed for someone else play pirate due to some errant info on your site.

P.S. Your site also apparently offers 2fa? I could never find where to enable this on your site.
