The whole point of this thread is about how poorly OnlyFans is managing this complex space.
Sites like OnlyFans could have mandatory training about not revealing sensitive details (close the curtains before you shoot, take your diploma off the wall, use a stage name, etc.). But yes, your face is a giveaway; and every day it becomes easier to turn a couple breadcrumbs into a full dossier of someone's life.
That's a practical proposal that would help.

But also possibly be besides the point: the internet doesn't keep secrets.
A choice to put content out there in public form, is de-facto a choice to make it available to anyone. Whether they paid the $10 or not.
That's a reality that has to be contended with wherever someone sits on the fence about the morality of it all.
I totally agree the content creators should assume the content will remain public forever and they will be doxxed at some point.
