In a nutshell, it seems that among their users, women are far harsher at rating men than men are at rating women.

Which is interesting in and of itself because in my real life experience women are much more likely to date men less attractive than them than the other way around. I guess maybe online girls get their own back? Or maybe the way they rate men and the ones they'll actually date are two very different things...
