Designed to prevent, counteract, or suppress rumors and false information.
From anti- (against) + rumor. Rumor comes from Latin rumor meaning 'noise' or 'talk.' The compound is modern, emerging with information management in the 20th-21st centuries.
Antirumor campaigns have become a big thing in the age of social media—organizations now actively fight false information, which is basically what everyone wishes had existed before the internet turned rumors into wildfire.
