I have wondered why there wasn't a bare-bones dating site. The basic CRUD app shouldn't cost too much to host, and could probably be run on an ad-supported model (perhaps with a subscription for a no-ads version). But moderation is not cheap. Women won't show up if they're going to be harassed. And men will harass women if you don't provide some kind of tools for preventing that. Bumble did a lot by the simple expedient of requiring women to make the first approach. That's not perfect, but it least it prevents women from being barraged with dick pics from every rando. Men get their own version: spammers and scammers. Which only gets worse now that chatbots can string men along cheaply. More openness is not a feature when it opens you to worse people. You need to think about these problems and build some kind of solution in from the ground up. You can't just leave them as problems to be solved later, or the jerks and criminals will ruin your app's reputation before it has a chance to get off the ground.
