You must post proof of ownership.
I am not trying to be rude or anything but you may have to pay someone to take this off your hands. Its a really ugly looking tag.
I recommend doing a giveaway or just junking it.
I give you credit for the effort. When i was knew to the gamertag sales i made shit tags myself. And i honestly still do sell shit tags.
Anyway, Just putting my honest opinion out there. Good luck on the site man. Remember to always post proof of ownership by screen shotting.
