"Useless Information" by Agent Smith -
The board member known as "Baley" is actually a virus:
"I'd like to share a revelation that I've had during my time here. It came to me when I tried to classify Baley's species. I realized that he's not actually a poster. Every poster on this board instinctively develops a natural equilibrium with the surrounding fora, but you Baley, do not. You move to a topic, and you multiply, and multiply, until every natural post is consumed. The only way you can survive is to spread to another thread. There is another organism on this planet that follows the same pattern. A virus. Baley is a disease, a cancer of this forum. Baley - you are a plague, and we are the cure."
