Appeals Committee. Disputed situations in tournaments.

I have an idea. Let's introduce a yellow timer in the game – a timer that shows how long a player has been thinking and hasn't made a move. For example, I'm playing against Sasha Kuzmin, and during the game, he decides to take a break, but I don't mind. He has a large yellow timer, but I don't report him, and everything is fine. But another player, let's say Vasya Pupkin, doesn't make a move for 5-20 minutes, systematically. And by turn 125 on JDB, I waited a total of 2.5 hours for him to make his move, which I reported with a screenshot. And it turns out that Vasya Pupkin has done this before, and he should be penalized. Because I no longer want to play tournament games with him. You might say that we can agree to play, for example, from 20:00 Moscow time to 00:00. But in reality, after playing for 1.5 hours, he leaves, and the yellow timer doesn't start, but this should also be penalized. And there should be a mandatory time limit for finishing games. I admit that I have also delayed games (I had little time + I didn't want to play when I was very tired)...
