Call of Duty: Modern Warfare Remastered Security & Enforcement Policy

"Boosting

Any user who colludes with another user to exploit the game for the purpose of gaining XP, prestige, game score, weapon level, or in-game unlock is subject to penalty.

First offense: User will be temporarily suspended from playing the game online, will have their stats reset, and will have their leaderboard entries deleted.
Extreme or multiple repeat offenses: User will be permanently suspended from playing the game online, will have their stats reset, and will be blocked permanently from appearing in leaderboards."

I have personally already been banned and reset as of today, it isn't worth wasting your time from now on boosting because you will most likely get banned.
