Don't answer this guy. Don't try to find anything else out. Do not send him ANYTHING. You've effectively reported him by posting here; I'm guessing an UW rep will be in touch with you to ask for details, screen shots, etc.
This is an unusual request and one we don't recommend meeting. Clients normally don't need this information and sharing your personal information you should provide. Will you please send me more information about this client through a private ticket so that I can check this for you? I was unable to identify the client on your account.
