Honestly, I think that you could probably even make something work if you had a one-time-only up-front fee, no advertising, and identification verification combined with criminal background checks (e.g., you couldn’t use it to cheat on your existing spouse, and all the people are real people). Heck, you could even set it so that if someone tried using it for advertising (OnlyFans or similar), you could permanently boot them off, since they’d need to prove identity to sign up in the first place.

Data security though… That would be a bigger problem. You def. would not want to have any kind of data breach once you had that kind of PII in your database.
