The string "marblecakealsothegame" (marblecake also the game) was used in a 4chan hack of the 2009 TIME 100 Poll, which manipulated the results of the poll so that the first letters of the top 21 names spelled out this string, and the top name was "moot", resulting in TIME Magazine pronouncing Christopher "moot" Poole, the founder of 4chan, to be the World’s Most Influential Person of 2009.

The string "marblecakealsothegame" could be used for any similar purpose.

marblecake

“The first Anonymous video message to Scientology and the first three themes for the protests were cooked up in a collective that has come to be known as marblecake, because of one of the names for irc channels they used. Opinions on this group vary widely. Some consider them a sinister, secretive cabal bent on controlling Anonymous. Others, including participants, portray them as simply a creative collective who brainstormed and came up with good ideas, which were then adopted at large on their own merits because they were good ideas. Critics of the marblecake group, on the other hand, accuse MC of astroturfing and using sock puppets to manufacture support for their ideas, “leaderfagging,” and otherwise being bad in a variety of ways.”
