Personal observation as a forum poster and a moderator:
People who post *anything* on a forum are by definition looking to get a response. Otherwise.... what's the point?
So the question then is: What kind of response is the person after, and is the content of the post against forum rules? PvP vidoes are by their nature a little more 'spicy' than PvE stuff. That alone is not a problem. When something is genuinely hurtful, spiteful, or targeting someone then we pull the plug. (Name and Shame videos are a good example). This particular thread is not one of those imho. People can legitimately have issues with the content, but it was unquestionably 'kosher' with regards to the games TOS and was a good highlight of player dedication and creativity. (I'm not advocating anything here - just pointing out that the content passed muster).
Personally I was impressed when I saw this video. Would i want to be on the receiving end of this? Of course not. Would I be royally cheesed off if I were destroyed? Yeah, probably.
Would I be against someone gloating over it a bit on the forum and holding it up as some interesting player-generated drama? No.
Edit: As a personal favor I'd appreciate it if people would stay on topic and not stick pointy objects in each other's eyes. And with that I recuse myself from modding in here further because now I'm fully engaged in the conversation. Be nice or Yaffle will come in here and no one wants to get on his bad side.
