I looked at the vandalism page, and I have not vandalized the Big O and Dukes page.

Vandalism is any addition, removal, or change of content made in a deliberate attempt to compromise the integrity of Wikipedia. The most common types of vandalism include the addition of obscenities or crude humor, page blanking, or the insertion of nonsense into articles.

Any good-faith effort to improve the encyclopedia, even if misguided or ill-considered, is not vandalism. Even harmful edits that are not explicitly made in bad faith are not considered vandalism. For example, adding a personal opinion to an article once is not vandalism — it's just not helpful, and should be removed or restated. Not all vandalism is obvious, nor are all massive or controversial changes vandalism. Careful attention needs to be given to whether changes made are beneficial, detrimental but well intended, or outright vandalism.

Committing blatant vandalism violates Wikipedia policy. If you find that another user has vandalized Wikipedia, you should revert the changes and warn the user (see below for specific instructions). Users who vandalize Wikipedia repeatedly, despite warnings to stop, should be reported to Wikipedia:Administrator intervention against vandalism, and administrators may block them.
