User blog comment:DatAsymptote/Admin Notice: Installing AdBlock/@comment-4214478-20151203194339

Adblock Plus was recently bought out by an unnamed company, which is almost certainly Google, and there's confirmation that other big (also unnamed) companies have been paying Adblock to automatically whitelist their ads. I've noticed personally that recently, there's been more and more ads getting through, including ads on youtube and tumblr, both of which I've gone almost 2 years without seeing a single ad on thanks to Adblock.

So, while Adblock may work for Wikia's ads (for now), if you're committed to blocking ads for good, I'd suggest installing uBlock Origin, also available on the Chrome Web Store. Not only does it use a LOT less CPU than Adblock does, there's no word of it whitelisting ads in the manner Adblock has. The only issue is that some scripts (especially on tumblr) you have to manually create in order to block, but this is easy to do. You just have to tell uBlock to block the offending element, and you'll never see it again.
