It should be obvious that nobody breaking the law has a right to anonymity and thereby avoiding consequences for breaking the law.
But I also believe that politicians should fight people attacking them by telling their side of the story not by suing. Politicians need to be reather thick skinned. They will be criticized, misrepresented, called nicknames, be targetted by totally made up stories etc.. Live with it or stay out of politics. Defamation of a politician is a funky concept as my guess is that 99% of politicians during their career get accused of something that is both bad and not true. And if they all went to court we would need to double the number of judges.
Threats are an entirely different matter. But that does not seem to apply here.
