I think the accused should have the right to legally challenge a public defamatory statement. In this case... it probably wouldn't be a very strong case, just from a quick google search, my guess is they would struggle with 1 & 4 below. For 1) In civil, this is probably preponderance of evidence (>50% true) vs beyond a reasonable doubt in criminal. For 4) Theoretically this has no impact, you are just screaming into the void and they don't even know about it. But it could cause real damage, this is a highly trafficked site, maybe they loose their job or their spouse sees this and divorces them etc. "To prove prima facie defamation, a plaintiff must show four things: 1) a false statement purporting to be fact; 2) publication or communication of that statement to a third person; 3) fault amounting to at least negligence; 4) damages, or some harm caused to the person or entity who is the subject of the statement." https://www.law.cornell.edu/wex/defamation https://www.law.cornell.edu/wex/defamation
