This has already been asked and answered in the private conversation we have. You report what you consider may be a troll and move on. You don't engage to even need to directly call them anything.Can you please explain to me how I am supposed to call a user who purposefully posts false facts with a malicious intent to prove his opinion?
It is a genuine question. Everywhere else on the internet such people are called trolls. What is the term for this here, so I know how to handle them in the future. I obviously cannot report such a person, because the rules do not forbid the posting of malicious false informations on this forum.
