Gmail 100 % usually tied to fraud unfortunately same with some dot .ca's the good ol go daddy route also another hint is Progressive insurance one of the most used for fraud as well. i mean criminals all be it somewhat smart there is a pattern they all take and its pretty much easy to figure it out.Quit using guys with free gmail or hotmail addresses. It'll save you a ton of headaches. If they cannot get an actual domain and an actual phone number to act like a real business they're only in it for the quick bang and gone.
