You need a both a good conversion rate from the part of the audience where you stand a decent chance of success in the long run and a sufficiently large number of 'samples'.

I think https://www.microsoft.com/en-us/research/publication/why-do-... discusses somewhat the same problem in a different context. It concludes:

"Finally, this approach suggests an answer to the question in the title. Far-fetched tales of West African riches strike most as comical. Our analysis suggests that is an advantage to the attacker, not a disadvantage. Since his attack has a low density of victims the Nigerian scammer has an over-riding need to reduce false positives".

Difference here is that most people wouldn't get the false positive ratio that the typical scammer gets so you probably should try a bit harder to look good on a dating site. I think hiding your baldness goes too far, though.

I think those who have a large amount of false positives know this. If, say, you need a wheelchair to move around, almost everybody would know it doesn't make sense to hide that, if the goal is to get into a relationship.
