I've noticed a pattern where great success automatically gets labelled as great intelligence, and the bigger the success, the smarter people say you must be. This always annoyed me: Mu5k, Bez0s and Einstein are not the same thing.
But nowadays I can see the other side of the argument. Countless people in sex work and on OnlyFans would love to have Bonnie Blue's income and reach, and haven't managed it. That gap must mean something in her field. She has some edge in marketing, performance, self-promotion (or whatever) that others in the same space don't have. She's at least knows enough to hire the right content and marketing people, if she didn't design it herself.
Whether that's "intelligence" in the classical sense, whether it would transfer to other fields, whether there are multiple distinct types of intelligence, those are fair questions. And I'm sure the answer isn't simply "yes, she's a genius."
I do think the people who say "X person (Bonnie Blue in this case) is so clever", are just using lazy language. But I feel the same when people say similar about businessmen, presidents etc. I remember people saying the same about the Kardashians, and Katie Price when she started writing books.
