What I am talking about is Hivewatchers posting a comment that wrongfully says something is plagiarised, when it is not. This happens. This is a wrongful statement of fact and may be defamatory.

I never even mentioned blacklists and I have made it clear that what I am talking about is when Hivewatchers gets it wrong (not when it gets it right).

@guiltyparties you continue to miss the point of what I am saying and keep attacking straw men.

What I am pointing out is that every time Hivewatchers gets it wrong and posts a comment saying something is plagiarised then it exposes itself to legal liability.

Although for completeness, in some jurisdictions (eg Israel & NSW before recent reforms) a statement can be defamatory even if it correct. In these jurisdictions one must prove truth AND public interest to sustain the defence.
