If someone were to make a statement that was known to be false, and someone else makes a defamatory remark in response to that comment, is it considered libel?
Say you review a restaurant negatively and they reply by saying we have no record of you ever eating here. You know this to be untrue. If you replied back with a negative statement like "seems strange that a cash payment wasn't recorded in the books". Since this is not an out of the blue comment suggesting a business acts illegally but rather responding to a comment that is clearly trying to damage the credibility of your review, do defamation rules still apply?
