BBB to answer your question............no, I don't think anyone is keeping count. I'm not and I've never seen any scam statistics posted here. Since you asked the question and have actually been involved in a "situation", would you be interested in being the board statistician on such things? Scamees could report their experiences to you and after a complete analysis you could report back here with conclusions and recommendations.

Your point, though, is well taken. The buyer should always beware. We all do the best we can.
