Facebook pretty much says that if you share too much alternative information, Facebook is not a friendly platform…
Starting today, we will reduce the distribution of all posts in News Feed from an individual’s Facebook account if they repeatedly share content that has been rated by one of our fact-checking partners. We already reduce a single post’s reach in News Feed if it has been debunked.
Your ass, dear Facebook user is now at the mercy of Facebook fact-checkers, and you might be of the impression that those are impartial people that have the common good in mind.
And do not be mistaken, I believe there are genuine purveyors of misinformation but do not ever believe that the fact-checkers always have good intentions. There will always be bias towards the official line, and that is totalitarian. Read this blog, and you will be informed.
I suggest you only post the mainstream media because despite them being the biggest purveyors of misinformation, they will likely never be censored. But I have a better suggestion, stop using a platform that is likely to censor you over things that should not be censored.
