Twitter: We Decided to Ban All Ads of a Political Nature

"We decided to stop political advertising around the world," Dorsey tweeted on his Twitter account.

That decision provides a stark contrast to Facebook and its CEO Mark Zuckerberg, who has spent recent weeks defending his decision to allow political ads of all kinds on its platform—even ones that contain falsehoods.

“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,” Dorsey wrote in a multi-tweet thread explaining the decision. “Political message reach should be earned, not bought.”

The new policy applies to political candidates as well as advertising around political issues, but will include exceptions for things like voter registration. The company plans to reveal a detailed version of the policy on November 15, and it will go into effect on November 22.
