Do people actually fall for this?

I thought this is the whole reason to use the blue check mark, so you can immediately tell real Elon from bot Elon.

But there are weird celebrity bots too. Eg, I followed Adam Sandler, and within a few hours a couple Adam Sandler bots started following me. They just had retweets of Adam Sandler tweets, but also a few hundred followers. Makes me wonders who are the people that follow these back, maybe just other bots?
