Facebook, Twitter 'too slow' to tackle meddling 😱 😨

Facebook and Twitter have said that they took too long to tackle foreign campaigns to meddle in US elections.

Responding to lawmakers, Facebook's chief operating officer Sheryl Sandberg said the social network was "too slow" to act on election interference.

Twitter's chief executive Jack Dorsey said his platform was "unprepared and ill-equipped" for the "weaponisation" of debate.

Google did not appear before the Senate Intelligence Committee hearing.

Opening the hearing, Democratic senator Mark Warner said he was "deeply disappointed" that Google "chose not to send its own top corporate leadership".

The senate committee is focusing on what the technology giants are doing to prevent future election meddling.

It follows claims that Russia and other foreign actors spread misinformation and propaganda ahead of the 2016 presidential election.

"With the benefit of hindsight, it is obvious that serious mistakes were made by both Facebook and Twitter. You, like the US government, were caught flat-footed by the brazen attacks on our election. Even after the election, you were reluctant to admit there was a problem," said Mr Warner.

He warned that the social networks could face new regulations.

"The era of the wild west in social media is coming to an end. Where we go from here is an open question," he told the hearing.

What have the senators asked?
Mr Warner asked whether Twitter would introduce an indicator to show which accounts were humans and which were automated bots. Mr Dorsey said Twitter had been "considering" the idea, and could label accounts as bots as long as it could detect them
Mr Heinrich asked whether a US citizen "intentionally spreading false information" would violate Facebook's community standards. He gave the example of somebody claiming the victims of a mass shooting were actors. Ms Sandberg said Facebook did not want to be the "arbiter of truth" and worked with third-party fact-checkers to identify misinformation. Stories flagged as false had their distribution "massively decreased", she said
Ms Collins asked whether the social networks would notify people if they had been engaging with fake accounts, once those accounts were identified and removed. Mr Dorsey said Twitter had not done enough. Ms Sandberg said Facebook had notified people in specific cases - including people who had indicated they would attend a fake event set up in Washington
Ms Collins asked why Twitter did not notify politicians that were the subject of misinformation campaigns by foreign agents. "I agree, it's unacceptable," said Mr Dorsey

How is Facebook tackling misinformation?
Ahead of the hearing, Facebook submitted written testimony outlining how it had disabled 1.27 billion fake accounts globally between October 2017 to March 2018. It said it employed 20,000 people to work on safety and security.

In July, the social network announced that it had removed 32 accounts and pages believed to have been set up to influence the mid-term US elections in November.

A month later it said that it had removed hundreds more "misleading" pages and accounts which targeted people in the Middle East, Latin America, the UK and the US.

Is Twitter censoring conservative voices?
Twitter's Dorsey will also face questions from the House Committee on Energy and Commerce about perceived conservative censorship on its platform.

President Trump has repeatedly accused Google, Facebook and Twitter of political bias and threatened regulation of the platforms.

In written testimony submitted ahead of the hearing, Mr Dorsey denied that his firm de-emphasised certain accounts in search results, a practice known as "shadow banning".

"Twitter does not use political ideology to make any decisions, whether related to ranking content on our service or how we enforce our rules," he said.

"We do not shadow-ban anyone based on political ideology."
