Ohhh, the great CL scammers, far too many of them these days... I think I have had just about every scam on CL sent to me over the years... I'm not sure how some people still manage get sucked into these things.
I have also seen a huge increase in scam ads on CL lately. Usually a professional looking pic of an item in pristine condition with a short must sell story containing very little useful info, and a price well below any known good deal.
I still use CL regularly with good results, but it does get rather tiring sifting through the endless scam and no reply responses.
