Plus, anyone who used the tactics you suggested, would easily be found out as an A hole, andno one would play any tournaments with them, or they could be removed by the director.
Also if someone did that to me, it would be easy to find a way to counteract this tactic.

I think it would be rare to find that combination of people you spoke of.
Most people don't play for only one hour at a specific time every day. And the odds of that being combined with an A hole who has nothing better to do with their time than to play games to harrass other players.

Again, I also don't see how doing that would actually cause someone to time out in the first place.

Another point, many games do not lend themselves to overall time limits because the amount of moves are not finite.
