It's not dark at all. It's just a place for people to list their kinks. Nothing nefarious. It's very popular in the kinkier sub-communities of the furry fandom.

edit: I got this mixed up with F-List, which is similar in function with a narrower focus.

There is definitely a seedy (read: illegal) element to the site which seems to have been going on for years without concrete efforts on the staff's part to eliminate. I'm not talking about kinks, I'm talking about pedophiles and rapists.

I got it mixed up with a similar site with the same acronym. I don't know much about FetLife.
