Yeah, it's too good to be true. These creeps are posting all over the site. Here's a checklist to find them:
1 - Member Since - usually today or within the past few days.
2 - No external contact information other than through the site. No phone number. No email address.
3 - FIrearm description often from the manufacturer.
4 - Stupid, often unpronounceable user name.
5 - Click on the location bullseye and you'll find Nigeria, New York, and other shitholes.
6 - Checkout the IP location for "Miami"
Suggestions: NEVER send money and expect a firearm to show up at your FFL if you can't verify the seller.
Get a phone number and at least make contact before anything. You should be able to sort it out from there.
Stay safe. - Frank
