Why am I still banned from the Xbox Ambassadors Program?

Ambassador issues are not handled by the forums. If you have a question about the program, you can contact Ambassador staff at xboxambs @ microsoft.com (remove the spaces), but bans from the program are typically permanent.

I never modded my gamerscore. I dont even know when nor why my gamerscore was corrected, but if i was removed from the Ambassador Program why am i still able to sign in and answer questions?

There has been an issue with the background check for the program not working correctly and not removing Ambassadors when it was supposed to. That was fixed yesterday which is why you were just now removed from the program. You can email Ambassador staff at xboxambs @ microsoft.com (remove the spaces), but as noted above, if you receive an enforcement action as an Ambassador, you are banned from the program.

and why am I in the ambassador program for the 360 and not the xbox one I hardly play 360 anymore

it says i'm not longer a ambassador but i still have my profile and all rank loot and xp. and i did not receive any email stating why i was removed from the ambassador program.
