Really sorry to hear you got scammed due to a wanted ad on Pinside. I try very hard to avoid this sorta thing from happening
Just so you know, I'm taking some extra action to avoid this from happening. Not disclosing what I'm doing, but just so you all know I take this stuff very seriously. Yes, I also contemplated sticky'ing Vids great guide, but don't want to hand scammers a "how not to be detected scamming people" on a silver platter.
Let me just stress this: be very careful when transacting online. Always use Paypal (and not the friends/family option) or your credit card (if it has good protection insurance) or a similar option, if you're doing business with someone you don't know.
Ugh, scammers suck.
