Seems like onlyfans is primarily in the adult content business, however, they appear to use stripe to process payments. Most card processors have clauses against supporting this type of activity, but it appears that Stripe is probably making a ton of money, given the growth of Onlyfans.

The adult payments likely don't go through stripe.
