He gave his account number. That should be more than enough for support, but we all know how it's going to end, right?
My guess is he will continue spamming this thread as he has been doing for the last 3 months. He won't even respond to suggestions to write a private message or email. That's what you meant, right?
Like it's something different than what you shills have been doing all this time. At least he has proof that he was one of their customers at one point. What do you have? Other than, of course, your impeccable reputation as a scammer.

At least you can be sure what to think about me, although I can guarantee you that you don't know even a little
I'm afraid that with number of account he can proof only that he was a 1xbit user. With that he can only spam this thread, but I see you like it.
