Every year, wikia increases the number and obtrusiveness of their in-page ads a lot on Christmas, just for that period.

Don't be so innocent to think they just made some rearrangements prior to their well-deserved holiday, and something went wrong which caused more ads to be present on pages. That's totally intentional. See for example, User blog:Ciencia Al Poder/December update - New ad formats for your visitors, quoting Sannse: the end of the year is always a heavier time for ads
