Not all users who saw that content, however, can take advantage of a new tool out today. Facebook has rolled out its new hub to help some how to find russian bots on facebook figure out if they interacted with Russian propaganda during the 2016 U. Kremlin-backed trolls on either Facebook or Instagram. Over the course of the 2016 election, Facebook estimates that roughly 140 million users may have seen Russian propaganda in their News Feeds or on Instagram.

Much of that content sought to sow social and political unrest around divisive issues like race, religion and LGBT rights. But only a small slice of those 140 million affected users can actually take advantage of Facebook’s new tool, which it first previewed in November. That’s because the portal only aids those who directly followed one of the accounts or pages set up by Russian sources on Instagram and Facebook. Facebook’s new service also doesn’t allow users to check if they saw some of the roughly 3,000 election-timed ads purchased by Russia’s notorious trolls, known as the Internet Research Agency. About 10 million users saw those ads around the election, the company previously has said. Its efforts have nonetheless won it some plaudits from Capitol Hill, where the company’s top lawyer — joined by executives from Google and Twitter — faced a full grilling this November for failing to thwart Russian disinformation online.
