One of the german guardian pointed this out in a post. I wanted to point this out more clearly for you in english.
It seems like that those users on ebay offer to "play for you" to get the redrix but onstead of playing they take your momey, your data and don't give you anything (that's only what I've heard!)
Please Bungie, take a look on this. If those users betray their clients, they need to be punished in law case.
Thanks for the attention.
