Facebook has no morality. It will publish anything. Haters, be they Nazis or Racists have a field day.
Propagandists can get their crap out to millions of eyes. People selling virtual ‘snake oil’ can get customers.
You can write a post which is pure fabrication and it will be seen and read as gospel.
The Owner doesn’t care. He cares about money. To get 1M hits on something which is vicious hate or lies doesn’t matter to him.
Politicians can post obscene lies about a competitor, claim anything, and it is posted.
Anything posted on Facebook which looks ‘true’ must be checked. Where did it come from? Did this news story come from the BBC or CNN or Nutwok News?.
