OK, so I got interested in the usefulness of OkCupid for neurodiverse people. Not that I'm really interested in a new relationship, but I can still play around to see how it works.
So I first registered (without changing my profile settings), and answered all 170 questions in the survey making sure I answered the sex-related one's indicating I had no interest in sex, and that a match shouldn't put high importance to this either (that was truthful, not an experiment). I didn't write a resume, and I didn't download a photo. Then I clicked on some matches. Not very convincing, at all. The girls weren't that bad, but no neurodiverse female in sight, and most seemed overly typical (and thus not very interesting). If I really wanted a date with this information, I'm sure chances would not be great. Also, it was not evident in any profile that OkCupid really had selected only people that didn't like sex. I would have needed to find this out myself. In addition to that, all my matches practically required monogamy and me being single.
Then, I changed my age preference from the default 33 to 92 years interval to 25 to 50. This resulted in some young matches, but none of them had my age in their own age preference, so this was clearly a bug in their system. This failure makes one suspect that other things are not checked properly either.
Next I decided to change my profile settings somewhat to narrow down things to see if this works in finding neurodiverse females. I filled-out all the profile settings, and specifically selected "married", "non-monogamy", don't require the female being single, and excluded short dating and sex-only (selected "friend" and "long dating" only). Then I looked at the matches again. The new matches were clearly a lot more interesting with several suspected neurodiverse females, and a few PhDs and other people that could be interesting for a friendship.
I think this shows that it is possible to find some type of neurodiverse females at OkCupid, provided you have somewhat divergent preferences and really express them also in your answers.
Edit: Checking some other things now. Put up the presentation now, and it is pretty unusual, I think (the intention is that it should be). I start by claiming I'm neurodiverse, asexual and polyamory. Of course, I say nothing about autism, as that has no relevance and would not attract positive attention. Still no photo, and I'm not sure if I want to put one up either.
