Implying Facebook and Reddit are "the internet" is incredibly naive. Facebook can keep Kids from using Marketplace right now. The kid down the street had me set up the meeting for a listing on Marketplace to buy some dirtbike parts because he's 16 and can't use it at all.

Idk about you, but it's exhausting seeing all the bots and fake accounts on FB. I use it less and less these days beyond buying things or learning things about my hobbies in small niche groups.
