To be specific, Jim means that it popups the alert about the site potentially hosting malware.

It redirects to a site called funnysignage_dot_com/r.php which is a 404 and Google doesn't like that site either.

The domain is still registered to Daniel Zimmerman who is one of the authors or was involved with the jEmplode project. The webserver that hosts Dan's main site is the same as what is hosting jempeg.org. Not sure why its redirecting. Something has infected the webserver?
