So, I do understand that it costs you money, but I'm agreeing with thot_experiment: it doesn't feel right, at least for the "victims of NCII" use case (as opposed to the "creator" use case with the $100/mo plan... I frankly think the pricing there is a bit high, but hopefully you've talked with enough sex workers to verify that works for them; honestly, if your website were focused more on that use case, and
downplayed the victim one, I'd find it more consistent).
Instead of a bunch of happy customers of your service, you are going to see people complain constantly about your product and consider you a "protection racket". You are also going to find yourself in the situation where the people you are helping are claiming you are "in cahoots" with the porn companies, particularly when they realize that they have to keep paying your subscription fee in order to avoid their stuff being posted again and again to different sites.
Some things are just asking for a world of hurt, and you need to really really play up the charity angle here and frankly attempt to fund as much of this as possible off of people who aren't the victims you are trying to protect or from a narrative perspective--which a lot of people don't spend enough time analyzing--you are going to spend the rest of your existence playing defense against your own target market feeling like you are part of their problem.
(My credentials here, with respect to talking about "narratives": I'm a well-known engineer who used to spend a lot of time attempting to correct the story developers would tell around jailbreaking and piracy--in some cases due to the mere word "jailbreaking", which I had not myself chosen as I wasn't there at the beginning--and who later went into politics and has been an elected government official in a dense college community for the past five years.)
