Does it mean that you had been trying to catch account seller red handed? But unfortunately seller already admitted it here. If this was your intention then you should inform suchmoon before communicate with the seller if he is agree or not. Or you should inform some other user who are active on this thread. Since you are unable to prove yourself innocent and you aren't trusted enough that's why you got negative feedback. Main thing you shouldn't involved suchmoon as a escrow.

For your information, seller admitted here when he cought red handed to me. Although I don't need to prove that I was just try to catch him and act like a account buyer but I informed to @dkbit98 in advance that I am going to talk with seller about account if he really want to sell it. So you should do same thing.
