I like it! Personally, I'd throw in the almighty Red stance of "Don't be a jerk!" at the end, but this goes far beyond that. In fact, I think this is better than don't be a jerk, and gives good examples of how NOT to be a jerk.
I think its important that people realize this isn't CoD or Halo, but a moderated game with a set of rules on behavior if you wish to play the game. If you have a bad game and feel the need to lash out on random people, do as I do and play those games. It's all background noise there at this point anyway, so you can de-stress yourself and come back a bit calmer. Typing out in caps will never be as satisfying as just shouting it all out.
Sticky request!
