Playing under someone else's profile is not against anyone's rules. The code of conduct exists here - assuming you're referring to "impersonation" of another person. No less than 50 people have played Destiny using my profile. It's probably a lot higher. I know that about 20 people have played on my wife's profile on 10 different consoles (I know because I own all of them). If it is my information, and I provide it freely, nobody has done anything wrong. That said - I personally feel people paying someone else to play a game for them is ridiculous. But if you have money - go for it. I'm sure nobody would be negatively impacted (obvious sarcasm).
