Well - maybe I should go looking more then. The half dozen or so BST pages I was a member of all got shut down or switched to purely discussion or accessories only. I haven’t seen a FS ad for a gun in months.
Of course craigslist has as the same policy, and if you are quick you can find ads before they get flagged.
Or you can just go through the traditional channels of the new paper ads, trade publication, or large websites like armslist.
Fun fact though - it is perfectly legal to sell a gun to another private individual as long as 1) you both live in the same state and 2) it is face to face. So you can’t mail it to their house (there are some exceptions, like if they have a C&R license and the firearm is on the C&R list - Curios and Relics). If they are out of state, you can deliver or ship it to an FFL in their state, and they have to go through the standard NICS check.
So this guy “has to do something” about something perfectly legal.
Is he also on Facebook flagging people posing with wads of cash and drugs? Careful now, I hear a lot of people are out and about looking for Pokemon. So maybe ask if they are looking for Pikachu before reporting suspicious activity.
ETA - in the groups I was in, they policed their own. Many wanted to see a CCW card or at least a license for a sale. Anyone one who was shady, and they usually stood out like a sore thumb, was flagged and kicked from the group.
The fear here is a criminal tricking a law abiding person into selling them a used gun. But that fear is akin to stranger danger - it happens but it is rare.
Also it is illegal to knowingly sell to a restricted persons, so must sellers take measures to protect themselves.
ETA II - Shit like this is why I have to show my ID and sign a waiver buying CHILDREN’S SUDAFED.
