The company wants to reduce the circulation of this type of content and avoid that they serve to profit.

In recent months is a battle between major companies with social content platforms against the spread of publications called fake news , the false news. The US elections of 2016 marked a before and after on this issue.

Google and Facebook have been very active throughout this year in taking action against this news, testing changes in algorithms and verification measures by third parties. The social network earlier this month expanded a testing tool since April to supplement publications suspected of containing false information with articles that add basic data to disassemble or give context.

Its last attack to these contents has been by means of the publicity. Facebook has reported that it will block ads on pages that share fake news . This is to prevent pages that have repeatedly shared publications of this type, therefore likely to contribute to the expansion of unverified content to make money with them, can advertise with them.

As explained two of the product managers of the platform, Satwik Shukla and Tessa Lyons, the company has found evidence that some pages have used the tool to create Facebook ads to reach broader audiences by false news.

Therefore, those pages that repeatedly share posts marked as controversial by external testers will not be able to buy more ads. If they stop publishing these contents, they can re-advertise this way.

The measure is part of the company’s global efforts against fake news , which is structured in three basic axes: attacking the economic incentives for its creation, building new tools that stop its distribution and informing people of what these types are of contents.
