Facebook is a double-edged sword, it is the largest social network where practically everyone interacts at any time, we tend to believe everything that is published on Facebook and this can (and does) accommodate fake news that go viral in a very short time.
Facebook doesn't like this, they don't want their social network to become an information center to disqualify people, countries or simply viralize something that shouldn't be relevant.
Para Facebook has just improved its filters to show truthful and quality news, avoiding false news or those that should not have a great impactfor the few verified data.
How does Facebook manage to show truthful news?

Thanks to an algorithm that works in real time, it is capable of detecting through user interaction if they begin to show a certain contemptfor the publication that is on the rise, Facebook will act so that it does not continue to expand.
This measure has been in the works for some time in specific countries, such as Germany, where gossip claimed that it was a plot about the political parties, basically so that they were not relevant.
It is true that many times we have seen publications that have been seen by millions of people making us believe that they were true. Being then false news or a content that varied too much with the reality.
Your content shouldn't be affected at first, but it could be beneficial for those that Facebook include as true and lower in display in all those that you do not believe are true or little relevant applying your filters.
What do you think of this Facebook measure? Is it really necessary? Do you think it will be effective?
