Twitter details political ad ban, admits it’s imperfect

Twitter says its new ban on political ads will cover appeals for votes, solicitations for campaign contributions and advocacy for or against political content.

Twitter’s new ban on political ads will cover appeals for votes, solicitations for campaign contributions and any political content. But the company quickly acknowledged Friday that it expects to make mistakes as individuals and groups look for loopholes.

Twitter is defining political content to include any ad that references a candidate, political party, government official, ballot measure, or legislative or judicial outcome. The ban also applies to all ads — even non-political ones — from candidates, political parties and elected or appointed government officials.

Twitter announced its worldwide ban on political ads Oct. 30, but didn’t release details until Friday. The policy, which goes into effect next Friday, is in stark contrast to Facebook’s approach of allowing political ads, even if they contain false information. Facebook has said it wants to provide politicians with a "level playing field" for communication and not intervene when they speak, regardless of what they're saying.

Response to Twitter’s ban has been strong and mixed, with critics questioning the company’s ability to enforce the new policy given its poor history banning hate speech and abuse from its service. The company acknowledges it will make mistakes but says it’s better to start addressing the issue now rather than wait until all the kinks are worked out.

In response, Democratic Sen. Elizabeth Warren, another presidential hopeful, ran her own ad on Facebook taking aim at Facebook CEO Mark Zuckerberg. The ad claimed — admittedly falsely to make its point — that Zuckerberg endorsed Trump for re-election.

Over the past several weeks, Facebook has been pressed to change its policy. But it was Twitter instead that jumped in with its bombshell ban.

Drew Margolin, a Cornell University communications professor who studies social networks, said Twitter’s broad ban is a reflection that “vetting is not realistic and is potentially unfair.”

He said a TV network might be in a position to vet all political ads, but Twitter and Facebook cannot easily do so. While their reliance on automated systems makes online ads easier and cheaper to run, Margolin said it also makes them an “attractive target” for spreading misinformation.

Because of this, the ban is unlikely to have a big effect on overall political advertising, where television still accounts for the majority of the money spent. In digital ads, Google and Facebook dominate.

Unlike Facebook, which has weathered most of the criticism, Google has been relatively quiet on its political ads policy. It has taken a similar stance to Facebook and does not review whether political ads tell the truth.

Twitter, Facebook and Google already take steps to prevent political manipulation by verifying the identities of some political advertisers — measures prompted by the furor over Moscow's interference. But the verifying systems, which rely on both humans and automated systems, have not been perfect.
