That's identity theft right there, using someone else's information for the goal of verifying a false account it in itself is a criminal charge even if you have the person's permissions. This wouldn't be really good at all for the ones who are interested since 20$ is very cheap for someone who is even willing to give up their information for money. For anyone who is interested in the offer right now I would ask you to think about it first since you are also will be liable for the crime if ever is something committed you'll be counted as an accessory of the crime and you'll have the same charge to whatever this guy will do impersonating you.
