This gets dredged up every few days. The sooner the reputation idea is implemented, the better things will become.
One thing to remember though, is that those people disconnecting after just hitting a bunker, obviously don't have much idea how to continue playing well after hitting a bunker, and at that rate never will. So not only is their average false, but their ability will remain average.
I irony is, that not only are they spoiling your fun of playing with someone, but they are obviously not having fun and getting frustrated. If they can't be bothered to keep going, they will just remain frustrated.
I find there can be more satisfaction sometimes in managing to save par after getting into trouble, than hitting some perfect shots and making an easy birdie.
