If you visit the link you'll notice that the Geocities bar is in place as usual, furthermore if you are taken in, the page you reach when you click submit looks like
this, and says
Member Form Email
The following form submission was sent.
user: USER
pass: PASS
pin: PIN
If you submit, once you reach this page most people would realize something fishy was afoot, and go change their stuff. Hopefull, anyway. It's not a very good scam.
