FB market place is wonderful never had a bad experience with it
There are still scum bags who try to run scams off FB Marketplace though.
The ones I see all the time are items like a used Kubota tractor advertised for a lot less than what it is worth.
Same thing with a John Deere lawn mower.
IF you click on the poster’s identity, their whole history is the same post of the tractor.
Then you press the ALERT tab on the AD.
