Twitter: We're challenging 10 million accounts weekly

From CNN's Brenna Cammeron

Jack Dorsey has admitted in the past that the company "hasn't done enough" to promote user transparency. But what is the company doing to combat the spam, abuse and misinformation that the platform has become notorious for?

Here are the main takeaways:

  • Relying on behavior: Twitter says it relies on machine learning to look at how accounts behave and react to each other to rank content in a user's feed. It says that since it started doing this, abuse reports have dropped 4% from search and 8% from conversations.
  • Finding the fakes: Over the course of the last several months, Twitter says it has identified and challenged between 8.5 million and 10 million accounts weekly that are suspected of being bots or creating spam. That's three times the 3.2 million caught weekly in 2017.
  • Combatting accusations of bias: Despite accusations of 'shadow banning' conservatives, Twitter says it has found nothing of the sort. In fact, the company says it ran a 30-day test following House and Senate accounts, and 'found no statistically significant difference between the number of times a Tweet by a Democrat is viewed versus a Tweet by a Republican."

Facebook: "This is an arms race, and we need to be ever more vigilant."

From CNN's Brenna Cammeron

Sheryl Sandberg is addressing the hearing now. "We were too slow to spot this and too slow to act. That’s on us," she said.

Here are some more highlights from her pre-released remarks:

  • Facebook by the numbers: The company says it has doubled the number of people who work on security and safety to more than 20,000. It says it reviews content in 50 languages, 24 hours a day.
  • Following the money: The platform says it has removed economic incentives to create fake news. It says it is blocking millions of attempts to register fake accounts every day.
  • Increased collaboration: Facebook says it is calling on government entities - including the DOJ, the FBI and other law enforcement agencies - to share information about threats and to work together to stop election interference in the future.

Wall Street is a little worried

From CNN's Matt Egan

Big Tech is coming under pressure from Wall Street as executives prepare to get grilled in Washington.

Twitter (TWTR) shares retreated 2% shortly after Wednesday’s opening bell. Facebook (FB) lost nearly 1%, and Google owner Alphabet was down a fraction.

Don’t feel too bad for the tech companies, though. Despite concerns about regulation, Twitter shares are still up 41% this year and Alphabet (GOOG) is up 14%. Facebook is down 3%.

Google: We are "deeply concerned about attempts to undermine democratic elections"

From CNN's Brenna Cammeron

Google is the only company that didn't send an executive to Capitol Hill, but it did release a statement.

The takeaways:

  • Google notes the measures it's already taken, including tools to increase transparency around who is purchasing election-related ads and how they are being disseminated.
  • It also doubles down on its efforts to improve the cybersecurity of political officials, as well as U.S. political organizations.
  • Notably absent was any mention of President Trump's recent claims that Google's search is "rigged" against conservative viewpoints.

Titans of Silicon Valley head to Capitol Hill

From CNN's Donie O'Sullivan and Oliver Darcy

Executives from Facebook and Twitter will appear on Capitol Hill today for Big Tech's third high-profile outing in Washington in less than twelve months.

Facebook COO Sheryl Sandberg and Twitter CEO Jack Dorsey will appear before the Senate Intelligence Committee Wednesday morning to discuss actions their companies have taken to thwart foreign influence campaigns targeting the 2018 midterm elections.

Dorsey will then participate in a second hearing Wednesday afternoon before the House Energy & Commerce Committee, where he is set to discuss the algorithms Twitter uses to serve content on users' Twitter feeds and "content monitoring." During that hearing, it's likely Dorsey will face questions about — and push back against — accusations of political bias against Republicans.

Google, on the other hand, will likely be a no-show.

Why isn't Google testifying today?

From CNN's Donie O'Sullivan and Jeremy Herb

The Senate Intelligence Committee invited senior leaders from Google as well as Facebook and Twitter, to discuss their role in "protecting elections from misinformation and disinformation." But Google declined to send a top executive. CNN's Donie O'Sullivan and Jeremy Herb explain:

Facebook COO Sheryl Sandberg and Twitter CEO Jack Dorsey agreed to attend. Neither Google nor its parent company Alphabet offered anyone from their C-suites, a committee spokesperson said. Google instead offered to send Kent Walker, its senior vice president of Global Affairs. Senators say Walker isn't senior enough. Senator Richard Burr told reporters that the committee would leave a chair and name plate open for Google.

So a senate panel on election security that’s being held just weeks before the midterms might just consist of Sandberg, Dorsey, and an empty chair.
