San Francisco • Twitter is banning all political advertising from its service, saying social media companies give advertisers an unfair advantage in proliferating highly targeted, misleading messages.
"While internet advertising is incredibly powerful and very effective for commercial advertisers, that power brings significant risks to politics, where it can be used to influence votes to affect the lives of millions," Twitter CEO Jack Dorsey said Wednesday in a series of tweets announcing the new policy.
Facebook has taken fire since it disclosed earlier in October that it will not fact-check ads by politicians or their campaigns, which could allow them to lie freely.
