This is the problem, at face value this happened and is now being used as evidence for the article's premise (which I enjoyed and agree with).
In reality it was a viral marketing move by onlyfans to promote porn on their website. You can't just come out and say to a bunch of Dads hey we got porn come take a look. But you can say hey we're banning all the massive amounts of porn we've got! oh no oops no we're not, all the porn you know and love is still there. We're sorry (TM)
Just like how no wives at some school are getting jelous how their husbands are looking at another mum's onlyfans... but I see paid articles about this all the time.
