Facebook halts more accounts as it fights election meddling

Facebook Inc.’s recent disclosures on blocking suspicious accounts show that the company’s efforts to root out election meddling are working — to a point.

What’s not known is how much the social networking giant isn’t catching and whether this “whack-amole” fight will ever end, as those wanting to influence elections in the United States and elsewhere can easily create replacement Facebook pages, groups and accounts.

Facebook said it blocked an unspecified number of additional accounts Tuesday because of suspected connections to foreign efforts to interfere in the U.S. midterm election through disinformation on social media.

That’s on top of the 115 accounts Facebook blocked earlier in the week and the 652 pages, groups and accounts it removed in August.

Facebook said the additional accounts were identified after a website that claimed to be associated with the Russia-based Internet Research Agency published a list of Instagram accounts it says it created. Facebook said it had blocked most of the listed accounts already and has now blocked the rest.

“This is a timely reminder that these bad actors won’t give up,” Nathaniel Gleicher, Facebook’s head of cybersecurity policy, said in a statement.

U.S. tech companies have stepped up efforts to fight disinformation campaigns by Russian groups, whom authorities accuse of swaying the 2016 presidential election. The companies were caught embarrassingly off-guard then. This time around, there are clear signs they are making some progress.

Sam Gill of the nonprofit John S. and James L. Knight Foundation, which recently commissioned a study on misinformation on social media, said that although tech companies cannot declare victory yet, “the leaders of the companies don’t talk any more that it isn’t a problem — they talk about how important it is to get it right.”

That’s in contrast to Facebook Chief Executive Mark Zuckerberg’s now-infamous quip in November 2016 calling the idea that fake news on Facebook influenced the elections “pretty crazy.”

But social media companies still have work to do. By some measures, the spread of fake news on Facebook has declined since 2016, but the same can’t always be said for Twitter.

The Knight study on misinformation points to a central problem that has emerged since 2016: It isn’t just foreign agents spreading misinformation. Plenty of homegrown sites are at it too.

The study found that fake news is still being spread on Twitter, the vast majority of it from just a few sources.

Gill said that at this point, we simply “don’t know enough” to say how the spread of misinformation has changed since 2016. That’s despite a slew of academic studies that try to measure the spread and consumption of fake news on these services.
