I'm pretty sure this is practically impossible.
Also Cowboy told me they have not accessed their FTP server so there's no way of them having our keys. Cca's just trying to stir stuff up.
Sorry for the double toast but I'd like to point out a few flaws in this.
First off, it is absolutely possible. I've done it myself to recover my own key once when I lost it, it's incredibly easy if you know how and the process could be easily automated to be done in the background by the server.
Second, he could easily be lying about what he has and hasn't accessed, and it might not even be him that's done it. He could be covering for someone else for all we know.
