I'm the one who was "claiming to have slept with his sister", but that was a long-running joke and who the hell thought that was anything but humor? He's openly admitted (on IRC at least) that he doesn't even have a sister. Please tell me: who has actually, seriously claimed to have met him?
Far too many people. Enough for you to have qualified for a scammer tag when this all collapsed and you proved not to actually know his identity.
You just lost all credibility.
