.. is anyone keeping count of how many scammers or would be scammers have done their thing here?

I got scammed, here. Yep.. guy posting for a nice unbelievably good condition Model 21 in 12 ga w/ 28" bbls; he couldn't believe the "low-ball" offer he got from Cabelas so posted it here.
After going through all the, what I thought to believe, right steps & questions, and seeing sufficient pictures he sent me, I bought the thing.
When It arrived at the transferring FFL, I went to see it. First off, without even picking it up, I knew the photos were artfully taken to avoid all the gouges and cracks, and the bbls were 30" not 28.
I never even filled out the transfer papers, called him from the shop & he was shocked that someone could be unhappy with it. About the bbls, he explained the 2" has to do with the chambers not getting measured into the bbl length. Just nuts. But, he did agree to accept it back saying he'd refund my funds as soon as it was returned.
Instead, when he got it back, he marched into Cabelas and sold it to them.
Just think, but by the grace of God, it could have been you.

They are out there, good people; be alert and alertful.
