I've experienced that a lot. Beyond that, Craigslist's anonymity makes it an easy vector for fraud, fencing stolen property, and other crime.
Yeah, but how much of a problem is that really? For instance, the last thing I bought on CL was a washer/dryer set, as my ancient washer finally bit the dust and needed a part that cost much more than a new economy washer. I seriously doubt the nice older lady I bought from had somehow stolen a washer and dryer to resell to me.
There's a big problem with things like stolen bikes and electronics and counterfeit or stolen (and voided) tickets.
Also, there have been numerous armed or strong-arm robberies by fake "sellers" who arrange a sale of a higher-cost item.
