I wish i had seen your post a few minutes earlier. I just flagged an ad on CL like I referred to and when I looked again it was already deleted. I would have posted a link for you to see one.

Usually the ad is not text, it is an image. In the image is an email address, usually gmail or one of the other "throw away" email providers, no phone. Most of the ads I see are cars, I like cars. The price is very often in the $2400-$2700 range and pretty ridiculously underpriced. I saw a post on a hacker website about the group one time and didn't pay any attention to it, should have.

I sold a truck on CL a few years ago that was in that price range. My ad kept getting flagged and deleted. I posted a plea in the ad to quit flagging my ad, call me, it's a legitimate deal. It finally stuck and I sold it. I was searching for the rational behind the flagging and deleting when I read the hacker post.
