How often do Wikipedia pages get vandalized?

Wikipedia’s defense against vandalism is layered, which is why most users never see vandalism on the pages they read. Anti-vandalism bots catch the obvious patterns within seconds. Editors with the article on their watchlist see new edits in real time. Tools like Huggle and STiki give experienced volunteers a continuous queue of recent changes to review. And on high-profile pages – Fortune 500 companies, prominent executives, contested topics – dozens or hundreds of editors actively watch the page. The practical implication for our work is that vandalism rarely lasts long enough to cause real damage on an actively watched article. WikiAlerts™ adds the comms-team layer on top: the moment a vandalism edit lands, the client team is notified with a diff and a one-click revert option, before any AI engine has cached or quoted the change.
