If someone walks up to my window and starts beating it in with a bat, I'm not going to sit and wait for the police, the police aren't going to fix the damage. I"m going to take out a pistol and start firing warning shots. Just sitting back and taking it isn't going to dissuade people from taking advantage of you.
If you really want an accurate analogy of this report system in terms of baseball bats and police, the flamer is the asshole with the baseball bat, you with the tazer keeping the guy from smashing your windows is you defending yourself, and Riot is the police who arrest you because you shocked the asshole to keep him from destroying your house.
You know, it reminds me of that episode of Drake and Josh where Josh dressed up as the Theater Thug for a TV show. It was funny up until everyone started ganging up on him, Josh got beaten by bystander 3 times, but HE was the one who was arrested each time, and then the cherry on the abortion cake that was that episode was when he got assaulted by the Theater Thug himself, the police show up, JOSH gets arrested, and the Theater Thug walks free. If that isn't an accurate analogy to Riot's report system, I don't know what is.
