@Troy You say you have closely monitored face book but you don't sound like you have viewed it through objective eyes. In your one-sided observations, you have presented the worst case scenario in regard to your vested interests.
For the majority of people, FaceBook is first and foremost a social forum. Or are its users as naïve and gullible as you think. They scroll down its board and pick and choose what they want to read. People soon get wise to the misleading head lines that don't live up to the hype and they are constantly advising each other in regard to fake news articles. FaceBook, itself, printed a list of the hashtags of unreliable news sources. Indeed, FaceBook is rife with skeptical people who doubt and pooh-pooh what is reported there. And users do have the option to stop receiving annoying notices that appear on their walls. "Delete" buttons are standard equipment on everything. Provocative memes are plentiful, and often humorous and on point. There are all kinds of quizzes you can take, and free photo-shopping for your pictures. There are a lot of food preparation and "cute" pet videos, as well as musical ones of old favorites. The discussions are lively and informative and trolls are easily spotted. Nobody forces you to look at the pictures people have posted of themselves or their children. Yes, FaceBook does bring out the worst in people who are stupid and vicious to begin with. But these types were around before FaceBook, and we'll always be around.
And do you really think the Russians had to convince black people that racism exists, or tell white people that BLM are troublemakers? Do you actually think if it wasn't for the Russians, all of the "deplorable" bigots out there would have voted for Hillary? These allegation themselves are over blown. There was just as much good posted about Clinton as bad. People weren't interested in the truth; they voted their prejudices. Mel makes a good point about this when she said: "...94% black women still voted for HRC... So while trolls may fool fools, it isn't fool-proof. Trolls are like a virus - if you're immune-system is strong (i.e., mentally strong) you can't become infected. Only a weakened immune system will be infected."
Social media is an amusement for me. And when I've had my fill of its vapidity, I click off and go to another site. There are millions of people out there like me who compartmentalize FaceBook. When it comes to its dire consequences, I think you are panicking like "Chicken Little" who thought the world was falling because an acorn fell from a tree and hit him on the head. In any case, you can't stem the tide of change. The future is fluid. This is the age of technology which is really just about enabling people to be more efficient at doing what they've always done and this includes exploiting each other. FaceBook is what it is, only as harmful or harmless as the people who go there. It is a mirror of life. Ubiquitous smart phones are more ominous.
BTW, do you think Mark Zuckerberg who gives millions away to philanthropic causes, who has admitted to not being a good watchdog and is trying to correct FaceBook's flaws, is out to control the world?
