just give me your gamer tag
No, You cant even Play on xbox live with a modded xbox 360 or modded game
If the two profiles are different saves, they should indeed be able to work on a single profile.
If you attract to much attention to your profile they may do both.
I can insure you that you will not be caught by Microsoft and banned, Microsoft can not track your consol but can track your online account, but it don't matter since you got your Xbox 360 modded into the hardrive not on your online account so therefore Microsoft cant ban you and you are free to download any content online.
If you use a modded controller you will be suspended from Xbox LIVE. A modded contoller is an Xbox LIVE Code of Conduct violation not a game rule violation.
I'm a Xbox Live Ambassador, and using a modded controller on the Xbox LIVE service violates the Xbox LIVE Terms of Use and will result in a suspension.
There is no charge to have an account with windows live. Windows Live is a free email service, in which a free account is set up, that can also be used with Windows Messenger and Microsoft accounts.
No
I wouldn't buy one as you can get a suspension from Xbox LIVE if you have a modded controller.
When you create an account on your console it automatically becomes an Xbox Silver Account (free account). But you can purchase an Xbox LIVE Subscription which you can't get for free.
No.
No . It's free.
