Raging over unimportant issues. Ragepolls in the middle of the fight happen maybe once per hour at peak time. Anyway, no matter that frequency I can guarantee it is lower than the frequency of actually valid polls for delayers/cheaters (pike on horse)/griefers. It's the only tool the players have against people being asshats without leeching or teamhitting.
Currently one person can only make one poll per map. If this is still too much for you, I don't know, you can learn not to be disturbed by the polls. I don't so it is probably possible.
