We developed a free social media application back in 2016 that cost us about $500,000 to build. We provided multiple safety filters including world filters, neural net pornography detection for profile avatars, etc. The application had a user profile search function. We had about 100,000 downloads in less than a year. I'm sure that 99.9% of user profiles did not contain any sexual material. Certainly less than Twitter has, where you can search for explicit porn. Google found a rare edge case that our ML model missed and removed the app from the Play store. With a single automated email half a million dollars was gone from my bootstrapped company. Is there anything I can do?
