The announcement and decision was explained in a series of tweets from CEO Jack Dorsey.
“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,” tweeted Dorsey.
“Internet political ads present entirely new challenges to civic discourse: machine learning-based optimization of messaging and micro-targeting, unchecked misleading information, and deep fakes. All at increasing velocity, sophistication, and overwhelming scale,” he continued.
Twitter did not announce the full policy about what it considers political advertising, saying that full details will be made available Nov. 15, 2019.
Policies will go into effect Nov. 22.
The company did note, however, that it will make some exceptions, such as select ads in support of voter registration.
