Sorry if I'm not supposed to ask here, I might have missed some rules.
I just want to ask how I should handle this last game - the host did a global mute right off the bat, then switched to our team after one of their members quit (I was on scourge, we were beating them pretty hard). After that, he kept farming forest, not helping the team and being a douchebag in general. When I told him to stop acting like that, he muted me. After that, he took some items I had in base (ultimate orb and blade of alacrity) and used his flying courier to drop them into the forest at the top of the map (checked replay).
The only rule he broke was the mute (although I did call him something just before the mute, so that one could be argued about a bit) and I broke some rules as I was no aware of them (I admit I only skimmed the rules before).
So short version: Can anything be done about a player who acts like an ass ingame (rude, doesn't assist team, uses courier to dump other player's items into the forest).
Edit: The thing above only happened once, but just now it was my second game where the host made an "apso noob" game, then used the -sdso mode and kept ranting about noobs. He admitted he was pro and that noone joins pro games, so he has to make noob games to get the people.
