Except for fan wikis. One that is on it's own website/different wiki site, and a lower quality wiki on Wikia.
Yeah but its kinda useless unless theres a point, like, most 2nd wikias have less stuff than the official one.
Some Wiki's on Wikia just steal content from the higher quality one. Teletraan 1/2 on Wikia steals a lot of stuff from the Tfwiki.
