I don't buy it. Something like that would make the news in Mississippi . . . not just Facebook.
A few weeks ago JFD extorted $$ from gun show vendors in Jackson, and that was on every TV channel my antenna picks up.
Saw on post on facebook a guy said ATF came to his house and gave him a 'warning" about him selling guns without an FFL but it sounded fishy. Knew a guy who got a warning from the ATF about the same thing but they did it at his table at gunshow, not at his house.
