Based on recent experience, FB doesn't have fact-checkers - actual people - up front. They have a moronic algorithm that looks for buzzwords and if one uses the super-wrong ones or enough ordinary wrong ones the algorithm hides the post and notifies the user, whose ability to respond is limited to agreeing with the hide or disagreeing. That a hidden post is no-tricks 100% accurate does not matter to Mr. Al Gorithm.
I disagreed with a hide and posted about it publicly, without word-mincing. Haven't heard back from Menlo Park (California, not New Jersey), and I'm still able to post.
