>> The next big platform for sharing.>> Facebook's Mark Zuckerberg once shrugged off the problem of fake news, but not it looks like it may just be the tip of the iceberg. Facebook for the first time acknowledging it's become a virtual battleground for government's seeking to manipulate public opinion, through means that go well beyond phony news stories.
And on Thursday, outlining policies to crack down on the perpetrators. Reuters technology report, Joseph Menn.>> One is so-called amplifier accounts, where false accounts that are not really an individual sitting in their kitchen or whatever, or on the bus updating their status. But it's actually a group of accounts controlled by a professional, or it could be by a government employee, they're all sharing information, liking information, spreading the word.
And if a lot of them do it at once, it is more likely to show up in other people's profiles their news feeds. So it's like an echo chamber, if you will, but it's part of a deliberate plot. What's interesting is that some of them may be sharing news that's actually true.
It's just that they're doing it in an automated fashion as part of a global strategy by Russia, or China, or the US, or whomever.>> And often done for geopolitical gains. Facebook now deleting those accounts, like it did in France suspending 30,000 ahead of last Sunday's first round presidential election.
Another problem is what Facebook calls targeted data collection.>> So, for example, a presidential candidate, a party official somebody like that, might be getting more than their usual friend requests. They might be getting a friend request, it might have been fairly well crafted. It is the name of an actual old friend they haven't seen sometime, but this time it's a spy.
And they're attempting to get a friend request accepted for example, so that they'd be able to learn more about the person who they're real friends are. And maybe trick them into opening a link that has malware to spy on them.>> Zuckerberg taking heat after saying in November it was a quote crazy idea that fake stories on the site could have affected the US presidential election.
Facebook now saying it does not contradict the intelligence community's conclusion that Russia was behind those efforts.
