MP Game: How bad is too bad?

[FAJ]

It all seems a bit moot, as nobody would sub in for a position where the previous player set it up SO badly that he had to be kicked. Now if there was a way to kick a player and turn his provinces into empty space which you couldn't enter, maybe you could correct the somewhat rare occurance of grossly mismatched opponents.

How bad is too bad? How long do you wait untill a player (such as myself!) has played very long and still is rotten at dominions? When do you send the suits in, beat him up and steal his hardcopy?
