In case this needs a little explanation… Everytime facebook censors, deletes, or creates a new algorithm it goes in tandem with one or two things. One, they're trying to cover their own pasty asses with the good graces of the public eye. Or two, its a co-op with mocking bird to help invent or strengthen a narrative. Last time I remember something similar to this happening was around the midterms.
