Could there not be a situation where a fake user confirms his or her identify with the help of a fake agent?
It's a big problem. What do you mean?
Potential agents also undergo a fairly in-depth verification process: utilities bills issued in their name and to their address, passport or other identification document, details of bank accounts that have been in existence for at least 45 days (this ensures another level of reliability, we do not want fly-by-night agents). We check those who will then check our clients.
