I doubt it, but it's possible the big ones are even more afraid of Wikia, inc. than the little guys. They're prominent wikis, and being shut down or kicked off the website would mean regaining popularity somewhere else. Not that Wikia's perfect PR personalities are scary to me, but maybe to the big guys.

Two more possibilities. These wikis might have a whole lot of admins, or feel that the community's opinion needs to be heard. Maybe they have so many users that they haven't decided on a census.

Lastly, Wikia might just be ignoring WoWiki, Muppets, etc.'s negative input like they do to the rest of us.
