As a former active spectator, this hurts. That's all I can say.
Also, I'm against the auto-kick option, not fair for all spectators that just like to enjoy watching the game.
I used to spectate a lot and I know players that like to do that too, like Blacks, or Pohnus. It is fun to see what are other players doing or just watch the game, to find other guys sabbing/cheating, etc.
The auto-kick option is a problem if you want to see someone in 1st view, because you have to move nothing in your computer while doing it.
