Anti-Vandal is a program that protects wikis all over the Internet from being vandalized. Anti-Vandal scans the wiki pages of its users for vanity pieces, spam pages, inexplicably blanked articles and sections of articles, and thinly veiled promotions for websites and blogs nobody cares about. The robust user community and open nature of Anti-Vandal has allowed for the development of a program that scans and stops wiki vandalism in real time.
