At the point where someone would lie about their results in a double elim., threatening to DQ them would hardly dissuade them from doing so. Again, it probably won't be a problem because the tournament doesn't have a bunch of anonymous members in it and it's good to look at it from a case by case basis, but I guess I'm looking at it form the perspective of if you were handling 50+ people (it would have been hellish if I had done that for mine).
It's just that I always feel it's better to never punish someone who wouldn't be at fault for other people's failings. Let's say there was a deadline a match was to be played by, but both players had not played it yet, I would only immediately DQ the player who did not notify me about it beforehand, not both of them.
Yeah, it's all about whatever works, in the end.
People should probably ensure they have proof of their match results, if they are able to do so.
