Unless I'm mistaken--correct me, if so... Wikia.com is a privately held company seperate from the WMF.
Why aren't links to all *.Wikia.com links covered by nofollow? A quick glance at the HTML source for example on the Wikia article on en.wikipedia.org shows that transcluded links to the privately owned Wikia pages are not covered.
Why does Wikia get the benefit of the SEO from Wikipedia? If there was an arrangement granted by the WMF for this, was it documented publicly? If so, where? Thanks!
