To me, it's about intent. If they are unknowingly wrong, they aren't lying. As soon as somebody informs them of the error, if they continue to report falsehoods, they are lying (and have now become fake news). It doesn't matter if the falsehood is generated by an algorithm or a person, or if the falsehood is malicious or not - as soon as they know they are wrong, they should take action to correct whatever has been published.
