I thought it was obvious enough from that signed message, but okay, here is new message with today's date and words from Charles-Tim: signed message

I'm 100% sure the new owner cannot sign message from any older address, but you can give him the chance, of course.

I bought it long time ago, I don't remember from who but I'm pretty sure it's not the seller who is operating the account now. It's someone else.

I'm not trying to claim it back, I'm just angry that someone stole it from me and I payed for it. So I want that you red-trust or ban this account because it has new owner so it's untrusted.
