u18chan.com is a weird site title, but I don't think it stands for 'under', rather 'you', as in, are you 18? That's my policy anyway, and it's not like it matters much, because the content we're looking at here is of the furry variety. Uh huh - not only furries though, gay furries. I'll be honest, I've never been a big fan of mixing animals with pleasure, but I guess if it's all safe and doesn't hurt anyone, there's no problem at all, right?
The current post count on /gfur/ is hard to determine, but it may well be in the hundreds of thousands. There's quite a big community here with the homepage having posts bumped up within a few hours of each other. Sadly, I was violated by seeing some of my most loved cartoon characters doing nasty things to one another, but that's exactly what you furfags want, right?! Enjoy, guys - go crazy and be sure to share your own gay furry desires on /gfur/.
