How about adding a BLOCK tab to your profile.
Because of the amount of quitters in wgt, it is very difficult to remember all those who quit on you during play.
If a player quits (and i would have thought 99% of us are intelligent enough to recognise a quitter from a disconnection due to poor internet or pc crash- i.e. the player quits just after a couple of poor shots and their score is in the +par range),
you should be able to add the quitters name to a Red flag list on your profile for future games. Then when you play a multiplayer game in the future and one of these quitters appears in your party, a red flag can come up next to their name for you to recognise them as quitters and then you yourself can opt out of the game BEFORE it begins and join another.
Hope this made some sense.
