Twitter became the latest social media platform to change its political campaigning ad policies Tuesday, announcing enhanced transparency features ahead of elections in Europe, India and Australia.

Social media companies, including Twitter, have faced criticism in recent years for their platforms’ role in spreading politically motivated misinformation and hate speech. As of March 11, Twitter will only allow certified advertisers to run political campaign ads on its platform in all European Union member states, India and Australia, as all three face major elections in 2019.
