I thought these were disproved by lack of gravitational microlensing?

The main way you’d see that kind of microlensing is if they aggregated.
But given the way gravity works, they should aggregate, otherwise why call them black holes?

If they were relatively evenly distributed would that counteract lensing?
InvertedParallax@lemm.ee 3 days ago
Yes, it would just be surprising because, gravity should make them not be evenly distributed.
The whole thing with dark matter is that it’s this magic stuff that causes gravity but isn’t affected by it, which… is not how gravity normally works.
Though there is still room for it, we just need a better framework other than “I added 3 and 5 and got 12, so obviously I must mean to add 3 and 5 and 4 too”.

You’re mistaken. Dark matter, whatever it is, isn’t affected by anything except gravity. It interacts with gravity just like “normal” matter.
The evidence is also significantly better than you’re describing
