Microsoft changes Services Agreement: Now requires you to sign in every 5 years to keep Gamertag.

Microsoft is updating their Services Agreement and the most notable change among many is the requirement to sign in every 5 years to mantain your Xbox Gamertag.

 
In the Microsoft Account or Skype Account section, we’ve added a requirement that you must sign into the Xbox Services at least once in a 5-year period to keep the Xbox gamertag associated with your Microsoft account. We’ve also added that if your account is compromised, we may be required to disable access to certain content.
 

This is something Microsoft should have done a long time ago. Many Xbox Live users simply quit the platform, and there was no way for players to get a Gamertag they would like because it was already taken. Microsoft also recycled nearly a million GT’s so players have a chance to change their name for something they like.
