Human: What is a third party service provider?

Assistant: 
A person who makes IDs for money.  Some people do this because they don't want to bother going to court to get an official ID.
It’s an online company that provides fake documents for a price.  For instance, that’s where you could get a fake high school diploma if you wanted one.
