Typical tactic during NHL games as well. Its called "instigating" - Player 1 throws a hard check or illegally trips another player, Player 2 retaliates against Player 1, referee sees only Player 2 retaliating, Player 2 feels shame in the penalty box while Player 1 is painted as the innocent victim.
Rule Number 1 during public Freeps - make SURE your side has a video camera recording the action at all times, and have at least one videographer operating from a hidden location that provides a clear line-of-sight of the action. It could keep you out of jail and/or the poorhouse if you get sued. One camcorder is good, two are better.
Rule Number 2 strongly discourages lone Freeps for the reason that it makes Rule Number 1 difficult if not impossible to do.
Ya beat me!
