Banning system suggestion

So, today I started a 3v3 bot game with two of my friends, just for fun. Next thing you know, I have to leave (for reasons justified better than parent freakouts), and every 3 minutes I have to scramble back to my computer and move my character around so I don't get disconnected (of course, my friends didn't mind. We didn't care when we started the game). Finally, I couldn't make it to my computer in time, and got DC'd. And I'm pretty sure that still counts as "Leaving a game," and even though that's only the second time I've ever left a game from level 1 to 20, I still feel like the system may misinterpret what happened and put me on the "look out, we might have to ban this guy" list.

I have an idea. At the end of a game, players can judge whether their teammate had a justifiable reason to leave. Or, if the server detects all three are in a party, leaving the game will not have any effect on your tribunal record, etc.

Just a thought. Tell me what you think.
