Are we not even going to talk about how many of their sites/wikis are filled with fake/misinformation and go to great lengths to document completely non-existent things in a way that isn't always obvious to outsiders?
Some, examples, here, however there are many examples that make absolutely no mention that anything listed is actually a "fanon".
Tux is a blackbelt in Karate, and has many combat skills including using Katanas and flips (which he learned from Kat and Ana). Tux also has an iq of 135. He's also a skilled Marksman. He's good at driving, can slide on his belly, and is resistant to extreme cold, being a penguin. He's also a good general, and of course, he's great at using Computers. Mostly Linux, but he can use Windows a bit too. He's especially good at Emulation.
LOL
At least I got a laugh out of it. It does seem pretty useless as a reference though.

I don't know how specific that is to Fandom but I am aware of at least one Fandom Wiki for an obscure old console game that's like 50% inexplicable unmarked fanfiction.
