I agree with this.
On the other hand I am also bitter towards people quitting games. Maybe I wanted to see the stats?!
Maybe if you quit two consecutive games in a row you can't play for 30 minutes. This would have room for error for that random drop/busy quit... but if you are quitting consistently you will have to wait!
I don't think we need hour/day long bans... I think we just need a half hour/15 minute ban to deter kids from quitting. Play the last 2 minutes out for gosh sake!
Sore losers.
