re: What is the endgame for all the stupid social media posts that ask simple questions?

That's got to be it as well. Because I notice the one my grandpa always answers just started a few months back and every post is simple questions. But digging deeper I see it's ran by a homely teenage girl.
Maybe a way to have tons of friends and engagement. On TikTok I understand it equals money. But I don't think you really get paid for followers on Facebook.
