Last year I listed some new brass for $50. Someone responded to the add, he did not use the PM. A scammer was going through the adds and sent the guy a PM and they arranged a sale. I had nothing to do with the sale and the buyer sent $50 to the scammer through Venmo and of course he never received the brass. He gave me a negative and called me all kinds of names, it took me a week to straighten this out. The moral of the story is don't respond to the add, always use the PM system.
