Vandalism

An example of a Wikipedia chad who adds the word "Sneed" to the end of many sneed pages.

On the internet, vandalism is the act of editing a website (usually a wiki) to introduce incorrect or nonsensical information, remove valid content, or otherwise disrupt the intended purpose of the website. Sneedposters often vandalize Wikipedia articles with the word Sneed in the title by adding a reference to the infamous scene from the Simpsons, usually being reverted by Wikipedia jannies in a matter of minutes.

Actions against vandalism on Wikipedia

On Wikipedia, if you include certain words in your edit (such as Sneed), it will trigger an "LTA 1137", which alerts Wikipedia Janitors that a certain page might've been vandalized.
