Re the word troll: Yes, I could have written that without using the word. The reason I did use it was a need for a label, since trolling is not an easily describable phenomenon (it implies not only endless discussions not aimed at resolving disagreements, but also a kind of rude behaviour, use of fallacies, personal attacks on the opponents and excessive amounts of generated text). Since there was a standard label for that kind of behaviour, I used it. I couldn’t think about other standard label with approximately same meaning which lacks the negative connotations, else I would have used it instead.
