Oftentimes, it isn't only a single game that results in a punishment, even though the reform card only shows one game. That's because the purpose of the reform card isn't to present an overwhelming body of evidence justifying the punishment; it's to tell that player to reform. There's no attempt at convincing the punished player that their behavior deserved a punishment, or that it was the right thing to do. By that point, that's all been decided already. The only remaining task is to put a stop to the negative behavior, for which there's no need to display a whole bunch of similar logs.
That said, I would certainly get behind a policy of punishing for one instance of particularly poor behavior, like running it down while spouting homophobic slurs. Currently, that sort of behavior is not necessarily immediately punished.
It is extremely difficult to get punished in this game.
