Twitter is to ban all political advertising worldwide, saying that the reach of such messages “should be earned, not bought”.
“While internet advertising is incredibly powerful and very effective for commercial advertisers, that power brings significant risks to politics,” company CEO Jack Dorsey tweeted.
Social media rival Facebook recently ruled out a ban on political ads.
News of the ban divided America’s political camps for the 2020 election.
Brad Parscale, manager of President Donald Trump’s re-election campaign, said the ban was “yet another attempt by the left to silence Trump and conservatives”.
But Bill Russo, spokesman for the campaign to elect Democratic front-runner Joe Biden, said: “When faced with a choice between ad dollars and the integrity of our democracy, it is encouraging that, for once, revenue did not win out.”
Reacting to the move, Facebook founder Mark Zuckerberg defended his company’s policy.
“In a democracy, I don’t think it’s right for private companies to censor politicians or the news,” he said during a conference call with journalists.
Twitter’s ban will be enforced from 22 November, with full details released by 15 November.
