I use Facebook a lot, but not for the social feed - Marketplace, business pages, and ads. I’ve never interacted with their “shorts” feature, and it’s all young women and girls in as little clothing as they can manage. It’s to the point that I don’t open the Facebook app in public. Ridiculous.
Offer up is dead in my area. Craigslist is a joke. Everything happens on FB marketplace. Vendors sell food, gyms liquidate old equipment, small furniture stores post their entire inventory.
FB isn't monetizing any of that beyond ads for related products, which I guess is how they monetize everything.
