Site's called Furvilla, which is a cutesy furry pet site. It was heavily advertised on Tumblr and Furaffinity, but a huge portion of users are from the former. The site was trying to be inclusive by adding around 16 genders to pick from when you register. But I think it's backfiring, because it's gotten swarmed with special snowflakes with a victim complex that attack anyone who doesn't follow their trend.
As someone who enjoys chatting on forums, the place feels unwelcoming as fuck. If you're not a "genderflux demiwolfkin" or some shit like that, you're a "cishet" and you suck, basically. And you have to walk on eggshells all the time with these people. If you say anything, even the smallest thing they don't agree with, they throw hissy fits, they call you transphobic, ableist, and so on. That and you might get blocked for no reason. In my case, the avatar I use there triggers them, me saying "neat" triggers them, and me pretty much doing anything triggers them.
I am currently a problematic person because I accidentally called someone a she, when they were a "demiboy". God forbid. Sucks I didn't take a screenshot, because the way they snapped was... not sure if pathetic or funny. Dem kids accuse me of transphobia and verbal abuse. Oh, they're also racist. There was this kid that said they were white and racist against whites... how does that even work?
You can view the forums even if you're not registered, in case you get curious. The game is cool to anyone who likes this stuff, but the comunity is toxic.
