As you all may know the prestige copy glitch copy's stats to your account from another account but what you did not know is that if you go look at the leaderboards your account will have the same stats as your old rank and the only thing that will look different on the leaderboards is your rank.

To sum this up the stats may look legit on your combat record but on the leaderboards everything is the same except your rank and treyarch will most likely issue resets or bans based on your leaderboard stats.
