Craigslist seems to be dying as people use Facebook Marketplace, OfferUp and LetGo to buy used items. The end of the personals section combined with heavy advertising by the aforementioned new entrants is causing a slow user bleed from Craigslist.
Craigslist over the past 2 years has had zero issues, I've interacted with fairly even keel 40+ year old people that are easy to work with. The "no lowballers, I know what I got" crowd has mostly departed Craigslist.
