There is no possible way to find people through xbox live. Me and my colliegs checked Xbox live when we made it. There is no possible way some could breack through the server.
Xbox live cards work on both kinds of xbox.
To find out if your xbox has live on it simply sign into one of your accounts, if the account does have live, it will say so. If not, you can purchace live at any time.
To find out go here: support.xbox.com/en-us/xbox-live/how-to/chat/terms-of-use-conduct Choose "Control communications on Xbox LIVE" to find out how to mute them, block their communications to you, or avoid them altogether. Choose "File an Xbox LIVE complaint" to find out how to report someone. Chose "Understand possible penalties: suspensions and bans" to find out what will happen if you report someone and Xbox LIVE finds out that the person did do something bad.
