Funny thing about those “unsuitable” people you’ve described: when they don’t get rewarded, and increasingly so for attention seeking behaviors, they find other outlets.
Then again, there’s little for personal growth like taking a breather from having to struggle for food and rent.
The worst thing about OnlyFans/porn is all the people who think as you do and consider those who “grow out of it” to be used goods. Definitely OOP and too many people today.
