XXXWarning do not click on the link above, unless you know what you're doing.

This page really doesnt do anything malicious, other than post a link to your facebook wall (which you can then remove manually) It serves as an educational tool to inform internet users anyone that happens upon it, as to how their privacy might easily be exploited.
Ironically it works in all the new browsers, like firefox, chrome and safari. This particualr example doesn't work in Internet Explorer - due to it not supposrting the CSS opacity With only 2 extra lines of CSS this also works in Internet Explorer.
