Yes I suggest not to create accounts without your nominee's permission because if they find out they might not like it much and then you would be in a big problem because they could take over your accounts. It is better to respect your nominee director. A nominee director who gives you a power of attorney to do things in company name does NOT mean you can use his or her personal identity for whatever other things you like. They are not being paid for that. What you are suggesting amounts to identity theft which is a crime.
