There's Otakubooty, but it requires pay to comment,pm, and post on forums, plus you're forced to upload pictures of yourself.

Yeah, unfortunately you're not going to find a dating site without all of it's important features locked behind a subscription fee. Much less one with a focus on this sort of thing. There's geek2geek, but again, everything is walled off behind a subscription so I wouldn't recommend it. I like that this place has a free forum, but it would be nice if I could actually look at people who match my area/age. Without that this is just a decent place to talk about anime and stuff. I'm pretty sure the people who run this place abandoned it long before I got here, anyways.
