Yes you are assisting him (a minor) in commit fraud.

So, that "his own decision" means crap.
In court he can claim peer pressure or what not and you will be booked too.
I would love to see the police try to find the real person who uses this account...
I said that my opinion would be to do it, but ultimately it is his decision in the first place...
