It's not as though the mods saw the first post and locked the thread. Several people disagreed with the thread topic and when they stated their opinion things started to go downhill and the posts were no longer about the thread topic but almost entirely just arguing.
If a post breaks the rules and gets deleted then complaining about it is like complaining when you get a parking ticket after parking illegally.
I can only imagine that they were sitting around discussing who would be great for the panel and Matt Cooke was suggested but unfortunately declined and then they flipped a coin to decide if they should invite Pronger or Neal.
The moderating on LGW is what keeps me around because I get to read threads that stay on topic and dont devolve into childish rants and personal attacks.
To say that LGW is "by far one of the most censored websites on the net" is probably a bit of an overreaction.
