I am absolutely in favor of using AI to combat unsolicited nudes as long as it's implemented something like: on the sender's side, show a warning before sending that the image appears to be in bad taste and asking for confirmation, then on the receiver's side, hiding the image behind a warning that it may be unwanted and showing two buttons, "show image" and "unmatch".
This is how Bumble appears to have implemented the feature. Though personally, I'm not going to test it because I think sending unsolicited nudes is a losing strategy for dating.
Yet, as rare as it might be, there are people of both genders who actually enjoy receiving unsolicited nudes. And people who enjoy sexual pickup lines. The judgement call of what is/isn't going to be attractive or appropriate ought be to left in the hands of the individuals dating as much as possible rather than controlled by a priest at a tech company.
