Just wanted to throw it out there (didn't see head's explanation in here before i posted).
#1 - You can change your fonts on skype
#2 - Many programs out there that can delete specific skype conversation histories, very easy to do
#3 - I never ignored any PM, I just don't use Sythe often, and when I did look recently, never saw a popup or anything saying I had a message
#4 - It's nice to know the victims of scamming can be banned when the person scamming can simply make a frivolous claim and delete a conversation to suddenly get off without any consequences. Not only did I get scammed, the other guy get scammed (both for almost $300 worth), but he also attempted to scam another guy right after the scam report went out which we promptly warned, trying to do the same thing.
But I guess as soon as you have some vouches, you can get away with anything, really is too bad.
