Get Someone's IP Through AIM/MSN/ Chat

Found a great website
that logs IPs and gives
you the lat/long./isp.
1)Create Account
http://
www.chatrack.frihost.net/
index-1.php
2)Get one of the links
and tell someone on
AIM or whatever to
click it, choose any of
the images and tell
them you painted it or
some stupid shit like
that.
3)When they look at the
image, it logs their IP.
4)Bonus points:
-Tell them its animated
and 20 seconds in it will
change, this allows the
website to have time
to ensure all their info is
retrieved.
