I already tried reporting him for farming the Real-Time ladder with his alts, but apparently nothing has happened since. I wouldn't be surprised if he stacks those lottery games with his alts to give himself a better chance of winning.
It actually is possible to boost your game count with "dummy 1v1s": set up a 1v1 with an alt, with no autoboot, start it and repeat without ever finishing previous dummy games. I used to do that when I needed an alt to look more active than it really was, so perhaps ALE has done some of that as well. 250 legit games would be impossible.....
The worst I ever had was 100 games, with 10 million points in the last 30 days (if I've remembered this correctly!). At one point, this made me the highest leveled player, with the most points in 30 days, for a week.
It's not cheating. I'd say 90% of those games are from round robin lottery tournaments, 2 territories, one with 1000 income the other with 1. All the lottery games in the tournament happen at the same time which means he plays all the 19 games at once. Multiply that by a few tournaments and you get 200+ games.
I played a bunch of lotto games so I could get to a high enough level to play in the ladders. I'm trying to counteract all of those cheap points I got earlier by blocking ads (nothing against ads, I just want to stop getting points).
