There was a league in my previous area where a team in our division was just awful. Awful in terms of how rough they were, I got tomahawked first game against them, then elbowed in the second (fights every time a whistle blew in their zone). The Refs would call egregious stuff when they could and suspend them for league review. But one of them was a friend of the rink manager or something so nothing stuck for long.
A few other teams captains and ours got together and started protesting any games against them, we sent a message and we told them that it was too late and we would not be coming back next Season.
