Blocks Game of Thrones spoilers from 9 gag... Currently if one of the following words appear in a post title, it will get hidden:
... some character names...
Note that it will not catch all spoilers! When someone doesn't write a GoT related word in the title, it will be displayed anyways. In principle you just shouldn't be on 9gag when you don't want things to get spoiled... Also, sometimes the 9gag is white for a second or two when you install this plugin, this is because it's checking the posts.
