I got banned because my gamertag was innapropriate. When i try to sign in it say in accordance to xbox live blah blah please change gamertag. When i click change gamertag it says you have to be signed in to xbox live then when i try to sign in it says to change gamertag over and over. How can i change me gamertag if i cant even sign in to live? How long do you normally get banned from having a innapropriate gamertag?
