Good idea, but people bubble chat each other all the time and do paypal. Again, if I put these rules in place and people trade with paypal and then get scammed.. My new defense is "You didn't follow the rules"

Then I'll get posts.. ZAB DOESN'T CARE ABOUT SCAMMERS, HE'S JUST HIDING BEHIND "You didn't follow the no paypal rules"

So again, this puts us in the same boat
