I would be suspicious of new users too. But as anyone can see, all I have done is offered Charles info and the link to SJPD(the local police). I have not may any offers to buy or sell anything so far. The reason why my post is posted here is I originally had interest in Charles's Pro Staff 6.0 but was suspicious of why any one would have so many rackets for sale, not to mention mainly expensive ones.
As for careful trusting the new user, all I have asked so far is for his email. As Topspin will later verify, the email I sent him has nothing in regards to personal deals or sales. I don't see how he's trusting me, beyond giving his email
