This is absolutely unrealistic there is something very fishy going on in here I just had a glance at the rankings and saw that the top 10 ranked players all have over 22000 wins and losses and draws on blitz, bullet, standard, etc Can you tell me how is this possible unless you live over a million years and constantly play chess every single moment. GOSH if this is real LOL that is absolutely LIFELESS!!!
What I think you're looking at is the staff at UBI who tested the game. I remember seeing their stats and other info on the first day the game was released. I'm sure it's nothing to worry about.
