I don't know BitcoinGirl.Club that well but he doesn't seem like someone prone to something like that. Leaking PMs to a shit-stirring noob is near the bottom of the list of things a sane ethically concerned person would do.
And then coming back as side chain to reiterate what was in the PMs after bidding the forum farewell, not pleased that their malice wasn't having the effect they desired... definitely not BitcoinGirl.Club.
