Hey Flyroh, If you are fearing that this person may act, please use the Xbox Live reporting feature to report them and also you can block that gamertag from contacting you further, but for the majority of the people out there that say they are going to hack
your account. Most of them are just lies to scare you. Also I would recommend visiting the Account Security for Xbox Live page
www.xbox.com/.../Account-Security for more ways to safeguard your account.
Did this solve your problem?
Sorry this didn't help.
