Terra Nova has a good discussion about in-game superstition and urban legends. When confronted by random behavior and rare events, people frequently make up explanations, some of which even sound plausible.
Funny thing is, occasionally they are true. Asheron’s Call really did have a Wi Flag based on character names. In the original A Tale in the Desert, wine flavors were based on the number of grapes that had been crushed in a barrel. In Kingdom of Loathing, you used to be able to change your odds of getting encounters by logging out and back in. Games have all sorts of oddities, which is why a seemingly harmless tweak can cause bugs throughout the game. You are in a non-linear feedback system where quasi-random systems can be based on arbitrary variables.
