I recently received an invite for "shtyle.fm".   If you never heard about it, you are in good company, as it can best be described as "Myspace's retarded cousin".Some facts about this screen that may to seem obvious at first glance:
- It's a mandatory part of the sign up process
 - It promises a free virtual teddy bear!
 - It requires you to fill in the credential of a real email account.
 - It validates the credentials, and throws an error if you give it fake information
 - The information is submitted and transmitted in the clear, over http, without any encryption (although the page seems to include an unused JavaScript implementation of RSA for some reason)
 - The page has (at least) a XSS vulnerability: Enter "+alert(1)+" in the email box (with quotes) and see what happens.
 - In case a connection is successfully made, the application will sift through your inbox for email addresses of your friends and send them personal invites in your name.
