In June 2008 Wikia decided to insert advertising inside the article space on their wiki pages. Since the wiki communities are hosted at no cost to the community members this is reasonable.
Notwithstanding the above, if you find those advertising blocks annoying then this style is for you.
The class/id for these ads has changed a few times so if you notice this style no longer works as advertised (sic!) then please leave me a message/suggestion and I'll keep it up to date with any recent change.
19-Mar-2013 - a few additional ad blocking filters added 14-Nov-2009 - stopped default filtering of avatars, sprites and masthead scorecard. Those filters are always available here at user's discretion. Just uncomment them if desired. 5-Nov-2009 - various additional/optional filters added - most are commented out so customize as you see fit! Most noticeable will be the filtering of avatars and sprites. You can easily comment those two lines out if you wish or leave polite feedback here and I may be persuaded to set that as the default.
