I mean, I feel like that's already probably true for dating apps in general - but I know what you mean. Post-date feedback would be a must-have. I don't know what you do with the dudes (and gals, for that matter) that are straight creepers, or anyone else that just has consistently bad dates.

I almost think you would need to have a bottom-of-the-barrel point where you straight up tell someone they need to seek out counseling and maybe provide some recommendations for soft-skill classes or some shit before they try dating again, then hit 'em with a 3-6 month ban to get their shit worked out before they come back and try again.

In theory you could scrub the feedback and give it back to users after enough time has elapsed to maintain some level of anonymity for the submitter. At least that way someone will see if they're consistently scoring low in "conversation" or whatever other applicable metrics and have an idea of what they need to work on.
