You aren't the only one...
It may not be PG13, but ever consider Diapered Anime?
After the place was resurrected we only had a few good posters around the forums, and not having many good posters lead to other good posters not being attracted... It's pretty much a negative-feedback loop.
I like the place since it is where I came from, so I occasionally try to get people to improve the place with their presence. <_<
