Boosting is a violation of Modern Warfare 3's Online Multiplayer Code of Conduct, as seen here.
I encourage you to review the Code of Conduct outlined in the link above and understand exactly what is and isn't acceptable when playing online in MW3 multiplayer. Boosting obviously falls under the 'do not do' category.
yes, i got deranked, i was prestige 6 level 66, and i didnt boost all the time , what can i do ?????
If you boosted ONE TIME, it doesnt matter.
There is nothing you can do in the future except dont boost anymore.
You may not want to boost or cheat, if Microsoft gets a report on you from anyone then they can and WILL permanently ban yor Gamertag from Xbox Live. You would then lose everything including all purchases, Download Content ,etc.
Even with Theater off they STILL have every single stat that you get in the game. They have full records.
