time points unfinished games

me thinks...... players who do not finish games and dont inform they can't finish and more likley, can't be bothered to finish (they are a pain in the neck).          Either because their losing, or they have mental problems, should be  be given a warning mark for all to see..........because I have found I have gained so many points by time faults, i would like to know if these people are worth playing and this would enable you to judge if they are worth the effort of starting a game,
