In Facebook announced on 22 November on the intention to the end of the year to create a special portal where users of the social network will be able to see, did they for the Russian advertising, which could influence the us elections.
Facebook has announced it is creating a tool to alert the roughly 150 million users affected by fake Russian accounts during the USA election.
"Personally, I think the idea that fake news on Facebook. influenced the election in any way is a pretty insane idea", he said.
Facebook said the portal is part of its continuing effort to "protect" its platforms and users from "bad actors who try to undermine our democracy".
Concerns about such Russian government-linked agencies have intensified in the wake of alleged Russian interference in last year's USA election, with claims that fake social media accounts were heavily responsible for helping spread misinformation and false stories.
With the new tool, users will see if they've followed or liked such a page from January 2015 through August 2017. He also sent letters to Google and Twitter.
Last month, Facebook revealed that people in Russian Federation had published thousands of posts via Facebook that were seen by up to 126 million Americans before and after Donald Trump's election win - with millions more Instagram users having also seen similar content.
Facebook is to take the unprecedented step of building a notification tool enabling members to establish whether they inadvertently "liked" pages that were in fact serving as Russian fake news sites. Democratic Senator Richard Blumenthal also called on the tech giants to alert consumers if they were exposed to the Russian-purchased content or ads.
Since then, revelations from multiple investigations into Russia's attempts to influence the USA election have led Zuckerberg to change his tune.
As many as 126 million people could have been served posts on Facebook and 20 million on Instagram, the company says.
US senator Richard Blumenthal hopes Google and Twitter follows Facebook's lead and create their own tools too.
