Terrible experiences happen to me way more on the newer platforms I listed. People are literally crazy on those new platforms, I've had death threats (from a user which OfferUp never banned) and various other threats on those 3 platforms. Facebook, OfferUp and LetGo all ignored my complaints.

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.
