Yes, I’m sure that’s true, probably for small items. I’ve never known anybody who’s had a good experience on Craigslist, but a lot of the people I have met have been renting places, trying to sell big ticket items, etc.
I think the fraudsters probably look for people offering or seeking something that is relatively high-ticket. Usually, they don’t kill them but just defraud them. However, there have been a number of killings associated with Craigslist, to the point that there was the famous “Craigslist Killer.”
Just last month I sold 2 forklifts for over $10K, and a $12k excavator the month before that, all cash deals,invited them to my house so they could inspect them. So it is not all crooks and scams.
