Major Nelson, Xbox Live community manager, reminded fraudulent Xbox users on Tuesday that account sharing and Gamerscore tampering will result in having one's account banned for life from the service.
"If you run into that person in Halo 3 who claims if they could have your LIVE ID name and password to recover your Xbox LIVE account to their Xbox and they'll rank you up or find you all the hidden skulls in Halo 3, I urge you not to fall to temptation," warns Nelson on his company blog.
Similar repercussions would be felt by those who artificially tampering with their Gamerscore or Achievements says Nelson.
"If you use tampered gamesaves to boost your Achievements and Gamerscore, you may sign in to Xbox LIVE one day and discover that we have removed your Gamerscore. Once we do that, you will never be able to re-earn those achievements on that account. Even worse, you might have your account and/or console banned from Xbox Live."
