In Dark's defense, some internet characters like Jeff the Killer, Sonic.exe, Zalgo, etc. don't have official artwork because the characters are entirely community-driven. Those ones I can see, especially if the fanart is done well. But if the page has a form of official or copyrighted artwork, that's what should be used.

The other exception I feel I can make if just a few high-quality fanarts are included in large galleries full of official images, and be cited as "unoffcial" artwork".
