Is it against TOS to give forum account away?

[Dragonsalt]

Just because something isn't written doesn't mean it's not bannable or against tos

On the contrary I believe that something that hasn’t been referenced to or explicitly stated in the terms of service can absolutely be done. The whole purpose of the terms of service is to inform the user of limitations, disclaimers, rights, and responsibilities. Now I agree that some parts of the TOS can be perhaps a bit vague to the point where you would be skeptical, but your situation seems rather specific. I wouldn’t worry about getting about getting banned. Playing it safe ain’t bad, just not nessecary for this case.
