Tim absolutely knows what onlyfans is. Not saying he has been there but any guy, and honestly any woman who says they don't know what it is is likely lying. It has received a lot of news and mainstream attention since it sort of blew up during covid.
My personal experience is that I have definitely clicked on links taking me to girls account pages. I have never subscribed to any because I don't really understand paying for pron. Yes, part of the allure is that there are more average women with accounts so it's not all the same plastic pron stars you see elsewhere, and you can "chat" with them... but from what I understand if it's a popular account with a lot of traffic you are likely talking to some sweaty dude who gets paid to run the accounts.
I know a woman who graduated from my high school several years before me who has one. I was on a date a few years ago and the (different) woman is telling me about one of her divorced friends who has one and makes good side money off it. Claimed it was a lot of foreign guys asking for custom feet videos, etc. Maybe it was her, who knows
I have a rarely used instagram account for following sports stuff and sharing dumb reels in a group chat and every time an onlyfans model pops up in my feed, it tells me that my cousin follows them. He must follow 1,000 onlyfans model IG accounts. I find it shocking that his wife allows this. I would think she would rather him subscribe to their content (maybe he does) and just watch pron. It's the fact that other people who they follow on IG can see who he is following.
