1) Report this game as a win. I've seen Hargen's attitude in AG and I'm not surprised at all at this.
2) To answer the question you asked in the beginning of that game: that depends on how you plan on doing that. If you're distracting them by insulting them, then no, it's not allowed. You can talk about trivial things all you like.
I think it's save to say that Hargen started in this game's chat though.
Solved. Hargen gets a green card.
