Y'all should consider this. People who repeatedly post specific lies which have been disproven by unimpeachable sources should be warned once and then banned, or maybe just banned. Two reasons: 1. Suppose someone, say, repeatedly falsely said Hillary Clinton has polio, after been shown to be wrong. If the site owner allows such lies to continue, then the site is being used for the most vile kind of disinformation - malicious rumor-mongering. (Note that this is completely different from saying such as "Hillary is an idiot", a matter of opinion.) Presumably, the site owners have not set this site up to be misused in such a way. 2. Allowing such material to remain on the site may pose legal liability for the site owner, insofar as it might rise to the legal standard of slander against even public persons - reckless disregard for the truth.
