Yes, huge +1 to this OP, especially if you're American bc you are heading for a big collision with FOSTA-SESTA and other legal issues that could put you and your users at risk of harm.
GP mentioned NCMEC, those guys don't care if it's generated or not. Anything aligns their preference gets labeled as "nonconsensual child pornography" and they come after your hosting, DNS, payment, visas, so on. Consensus or IRL children aren't their concerns.
Ultimately they'll flashbang you on a Sunday morning, put you on a no-fly list, and circulate warrants, at least until you add heavy geoblocking and start framing them right so they'll be the socially awkward side. They won't ask you for a list of clientele, they can look that up, they're after contents.
