Somebody hacked into Facebook’s system and added a period to their url address after the com = facebook.com.
At least that’s what my iMac reported. There is a typo in the url address for facebook.com.
That should mean that no one could manually log into or automatically post to Facebook.
In the news a few days ago was a prediction that there would be a huge cyber attack against Facebook. Guess they had inside knowledge from those who orchestrated the attack.
Maybe Facebook did it themselves to quell the chatter about Facebook practices and policies that were hidden enough to require a whistleblower coming out of the closet in protest.
