Same Person Adding me on different Accounts with same Gamertag

When it's unknown Amount of Accounts Blocking is useless. Everytime he Adds me it's a Different Account with the same Gamertag just with different numbers at the End. There needs be a way to Report him even it's through Xbox Support this type Behavior
should not go unpunished. Harassment is against the Code of Conduct yet somehow this Behavior is Tolerated even though it's Harassment.

Hi BladeNBatman.

I would recommend blocking those users that you don't want following you.

When an individual is added to an Xbox LIVE Gold Family Pack, that person’s Xbox LIVE account must be on the same console as the primary account holder. However, once they are a part of your Xbox LIVE Gold Family Pack, that person could recover their account
on a different console and still remain a part of the Family Pack, as long as they reside in the same country as the primary account holder.

Hi;

Unfortunately, there is no possible way to link same Gamertag to a different account email. the closest to that is what you mentioned, adding another email as alias and make that alias as primary signing email.
