I see scam sale ads in every eBay category where it doesn't cost money to post ads. Look at the boats section especially. Around here I'd guess 2 out of 3 are obvious scams, and half the remainder are less obvious. Housing too. Before I even had a chance to post our latest rental house for rent... some scammer swiped pics from the listing on Zillow and posted it for rent on CL for $200 per month less than I listed it for. I contacted the scammer to see what the angle was. He wanted a deposit of a few hundred bucks before showing the house... of course it's FULLY refunded if you don't rent... yadda yadda. Everything was via text messages, he ignored repeated requests for an email address and of course no one ever answered the phone number. I set up a time for him to show me (MY) house... but of course he kept insisting on a "deposit".
I finally asked him how exactly he intended to show me the house when I was the only one who has keys for it, since it's MY DAMN HOUSE. Radio silence after that. of course. Craigslist has no way of reporting anything like this, of course. They don't care and take zero responsibility for anything their site is used for. If ever a business was ripe for a massive class action lawsuit...
