I've been off of Facebook for several years because I find it mostly annoying, but I have some stuff for sale and I'd like to post it on the FB marketplace. But, what is up with their ads? I see Jeep Wranglers in good condition, for instance, listed for prices like 1400.00. They might be ten times that. The car prices seem absurdly low, as do a number of other items for sale. What is going on here?
