LOLSPAM

LOLSPAM is the pointless waste-of-database-space crap that gets posted that no-one can even be bothered to read.

Background
LOLSPAM started a billion years ago in the General Discussion Thread, which turned into a battle of who could post the most pointless random images in response to every person who tried to make a half-serious post.

Impact
LOLSPAM led to the creation of the Social Club.
