Do I restore the post or do I leave it deleted?
My answer: I restore it.
Why? Because I can not determine that the post is "libel" and neither can the person who deleted it. If the person deleting it says that he knows the post is untrue and therefore libel, that's not good enough for me. I would have to take him at his word. And even if he says he can provide me irrefutable evidence that the post is a lie, it makes no difference to me. Once I make the call that the post stays deleted because it's libel, guess what. I just asserted on behalf of Investors Hub that every single post ever written on it is true.
If anyone recognizes certain aspects of that hypothetical scenario, it's because a very similar situation happened years ago (and similar ones happen daily), and at the time the proof that the person had libeled the company and CEO was that his statements were in direct contradiction with company press releases and SEC filings.
