The ban, which begins November 22, will apply to all ads with political messages.

“We have made the decision to stop all political advertising on Twitter globally. We believe that one should not pay to reach out with a political message, but deserve it, ”writes Twitter CEO Jack Dorsey in a statement on the platform, adding:

"While Internet advertising is very powerful and very effective for commercial advertisers, this power poses significant risks to the policy."

The ban is criticized

US President Donald Trump has made himself known as a frequent Twitter user, and the ban is now being criticized by Brad Parscale, Trump's campaign manager for the 2020 presidential election.

"Twitter's ban on political ads is yet another attempt by the Left to silence Trump and conservatives," he writes on Twitter.

Pressing Facebook

Social media platforms such as Twitter and Facebook have in recent years been criticized for spreading ads with incorrect information. Among other things, Facebook has been accused of influencing the 2016 US presidential election with Russian propaganda ads.

The fact that Twitter now bans political ads is increasing the pressure on Facebook - which has made the decision not to fact-check ads from politicians, according to Reuters.

According to analysts with Reuters, the ban is not expected to affect Twitter's finances, but the company's share fell 1.8 percent after the ban was announced.
