Yura, calm down already. I haven't read these rules any more than you have, but I know for sure that malicious trolls get banned on any forum according to the rules, just like those who think they're the smartest and start lecturing the administration.
So everything written here is concentrated experience, the product of difficult mistakes — both my own and those of others that I had the opportunity to observe.
For example, the story you're familiar with regarding the Heroes 3 movement on HL — the mass exodus of online players from there happened precisely because of the administration's unwillingness to learn, admit their own mistakes, and find a common approach with players. I have observed many similar examples on a wide variety of forums. And I think you have too.
