I think it's worth reporting that to chess.com staff. Surely there is something wrong here. If your games have a 3-day limit, then even if you play 16 hours / day, 1 move every minute, you would only be able to play 2880 games (3 * 16 * 60).
3035 games

What is amazing is that he is 7-3 in his last 10 games. Maybe he is shooting rom the hip and making moves in within seconds??? Could be a real genius with a lot of time.

Two moves per minute = 2*60*24 =2880 moves per day. Assuming 8 hours of sleep = 2*60*16= 1920 moves per day. I guess it could be done, but I still have to use the word from my original post: WOW!!!

Of course you only need to count 1012 games per day. If he spends 10s on each move, he would need 3 hours to go through them. At such a rate it is not possible to play as accurate as this guy, who manages to have 1500+ rating. Especially since he is not an incredible chess genius, as his other ratings aren't very high either.
Is there no limit? I am playing a 1500 rated player that is currently involved in 3035 games. I probably would not have noticed, but he gave me his queen basically for free, and now I am wondering if his account has not been compromised. I am going to do a little research, but wow, 3035 games. That is more than I have played in my life.
