There's money in online dating, so why would appropriate action be taken against a reliable revenue stream?

It would easily be possible to build functionality into the Apps that allow recording of when a woman (and it usually is a woman), has to block a man (and it usually is a man), just by recording the machine-generated user_id, so that if x-number of women black the same man, then it alerts the controllers of the App, so that the account can be either suspended or deleted, foregoing any remaining subscription time.

But they won't do that, for reasons of making money.
