Accounts question

[Wubsie]

The problem is: You are not allowed to play someone else's account.

Not quite sure if they make distinctions for even immediate family (apart from children playing accounts their parents own and control), but I would tread lightly since especially as you've mentioned leveling a character for another person, this, in my non-expert opinnion would fall under account sharing, which will get all parties involved perma-banned in a hurry.
