On September 3, 2020, Mark Zuckerberg published a lengthy post on his personal Facebook profile, detailing dramatic new measures Facebook is undertaking to safeguard the integrity of the U.S. elections. Zuckerberg wrote [we've added topical descriptions in brackets]:

Today, we're announcing additional steps we're taking at Facebook to encourage voting, connect people with authoritative information, and fight misinformation. These changes reflect what we've learned from our elections work over the past four years and the conversations we've had with voting rights experts and our civil rights auditors:

• [Reliable Information at the top of page] We will put authoritative information from our Voting Information Center at the top of Facebook and Instagram almost every day until the election. This will include video tutorials on how to vote by mail, and information on deadlines for registering and voting in your state.

• [No political ads starting the week before the election] We're going to block new political and issue ads during the final week of the campaign. It's important that campaigns can run get out the vote campaigns, and I generally believe the best antidote to bad speech is more speech, but in the final days of an election there may not be enough time to contest new claims. So in the week before the election, we won't accept new political or issue ads. Advertisers will be able to continue running ads they started running before the final week and adjust the targeting for those ads, but those ads will already be published transparently in our Ads Library so anyone, including fact-checkers and journalists, can scrutinize them.

• [Partnering with state election authorities to identify election misinformation] We're going to extend our work with election officials to remove misinformation about voting. We already committed to partnering with state election authorities to identify and remove false claims about polling conditions in the last 72 hours of the campaign, but given that this election will include large amounts of early voting, we're extending that period to begin now and continue through the election until we have a clear result. We've already consulted with state election officials on whether certain voting claims are accurate.

• [Limit the number of chats you can forward on Messenger] We're reducing the risk of misinformation and harmful content going viral by limiting forwarding on Messenger. You'll still be able to share information about the election, but we'll limit the number of chats you can forward a message to at one time. We've already implemented this in WhatsApp during sensitive periods and have found it to be an effective method of preventing misinformation from spreading in many countries.

• [Remove both explicit and implicit voting misinformation] No political ads starting the week before the election] We're expanding our voter suppression policies. We already remove explicit misrepresentations about how or when to vote that could cause someone to lose their opportunity to vote -- for example, saying things like "you can send in your mail ballot up to 3 days after election day", which is obviously not true. (In most states, mail-in ballots have to be *received* by election day, not just mailed, in order to be counted.) We're now expanding this policy to include implicit misrepresentations about voting too, like "I hear anybody with a driver's license gets a ballot this year", because it might mislead you about what you need to do to get a ballot, even if that wouldn't necessarily invalidate your vote by itself.

• [Remove COVID-misinformation to scare voters from voting] We're putting in place rules against using threats related to Covid-19 to discourage voting. We will remove posts with claims that people will get Covid-19 if they take part in voting. We'll attach a link to authoritative information about Covid-19 to posts that might use the virus to discourage voting, and we're not going to allow this kind of content in ads. Given the unique circumstances of this election, it's especially important that people have accurate information about the many ways to vote safely, and that Covid-19 isn't used to scare people into not exercising their right to vote.

Measure to stop false or premature election results 

Since the pandemic means that many of us will be voting by mail, and since some states may still be counting valid ballots after election day, many experts are predicting that we may not have a final result on election night. It's important that we prepare for this possibility in advance and understand that there could be a period of intense claims and counter-claims as the final results are counted. This could be a very heated period, so we're preparing the following policies to help in the days and weeks after voting ends:

• [Facebook Voting Information Center provide information on time it takes to count votes] We'll use the Voting Information Center to prepare people for the possibility that it may take a while to get official results. This information will help people understand that there is nothing illegitimate about not having a result on election night.

• [Partner with Reuters and National Election Pool for authoritative information on relection results] We're partnering with Reuters and the National Election Pool to provide authoritative information about election results. We'll show this in the Voting Information Center so it's easily accessible, and we'll notify people proactively as results become available. Importantly, if any candidate or campaign tries to declare victory before the results are in, we'll add a label to their post educating that official results are not yet in and directing people to the official results.

• [Label posts that attempt to deligitimize the election results] We will attach an informational label to content that seeks to delegitimize the outcome of the election or discuss the legitimacy of voting methods, for example, by claiming that lawful methods of voting will lead to fraud. This label will provide basic authoritative information about the integrity of the election and voting methods.

• [Expand Facebook policy against content with violence and harm directed at election officials] We'll enforce our violence and harm policies more broadly by expanding our definition of high-risk people to include election officials in order to help prevent any attempts to pressure or harm them, especially while they're fulfilling their critical obligations to oversee the vote counting.

• [Expand Facebook policy against militia and conspiracy groups organizing or supporting violence] We've already strengthened our enforcement against militias, conspiracy networks like QAnon, and other groups that could be used to organize violence or civil unrest in the period after the elections. We have already removed thousands of these groups and removed even more from being included in our recommendations and search results. We will continue to ramp up enforcement against these groups over the coming weeks.

It's important to recognize that there may be legitimate concerns about the electoral process over the coming months. We want to make sure people can speak up if they encounter problems at the polls or have been prevented from voting, but that doesn't extend to spreading misinformation. We'll enforce the policies I outlined above as well as all our existing policies around voter suppression and voting misinformation, but to ensure there are clear and consistent rules, we are not planning to make further changes to our election-related policies between now and the official declaration of the result.

In addition to all of this, four years ago we encountered a new threat: coordinated online efforts by foreign governments and individuals to interfere in our elections. This threat hasn't gone away. Just this week, we took down a network of 13 accounts and 2 pages that were trying to mislead Americans and amplify division. We've invested heavily in our security systems and now have some of the most sophisticated teams and systems in the world to prevent these attacks. We've removed more than 100 networks worldwide engaging in coordinated inauthentic behavior over the past couple of years, including ahead of major democratic elections. However, we're increasingly seeing attempts to undermine the legitimacy of our elections from within our own borders.

I believe our democracy is strong enough to withstand this challenge and deliver a free and fair election -- even if it takes time for every vote to be counted. We've voted during global pandemics before. We can do this. But it's going to take a concerted effort by all of us -- political parties and candidates, election authorities, the media and social networks, and ultimately voters as well -- to live up to our responsibilities. We all have a part to play in making sure that the democratic process works, and that every voter can make their voice heard where it matters most -- at the ballot box.
