A lot of wiki's on Wikia are "gaming" wiki's. So what has likely happened is that they've placed a wildcard block on wikia.com (ie *.wikia.com), so no matter what wiki it is, they're all blocked under the web filter as "Games". Most likely the site has been blocked by your corporate because it was determined the sites are detrimental to their network, which happens all the time (my non-Wikia site is blocked by a council's "school web filter" for no real reason lol)
