Anybody playing 1000 games and making 1 move every minute would need slightly over 16 hours to make a move in each game. Assuming that even 10% of the opponents are on line and move on the same day, he would then have another 100 or more moves to make. That leaves precious little time for sleeping, eating, going to the toilet, interacting with real human beings, browsing bulletin boards, watching television, shopping, going to the movies. I don't believe that anybody needs to be signed up for more than about 2-300 games concurrently, let alone join a tournament if they are already playing 500 or more games. I have just turned 70, and am still locked into a tournament which started when I was 65, and in which I have not made a move since I was 66. I am likely to time out in the final round(s) simply because I will probably be residing underground before the tournament finishes. That should help to prolong the tournament for another 5 years while I time out involuntarily.
