if this is what you call predatory, then why isn't sports stars and film/music celebrity culture not predatory in the same way? I don't see the difference.
I say let people do what they want, as long as they understand what they're doing and is informed of the (potential) consequences.
You’re right, no real difference.
So when you don't get drafted, there is a little problem...
Onlyfans is stupid, hopefully noone has faced violence in the real world from it.
If you fail at OnlyFans, then everyone whoever lives for the rest of history can possibly see you nude / playing with yourself / having sex aka 'doing porn' of some threshold for the rest of time. This may not be a problem for some, but for large swaths of others it will be, especially for quantities of individuals who have second thoughts and regret their decisions.
The consequences are not very comparable.
Maybe things will change in the future (i.e. privacy laws etc)
