pornisart.com is hotlinking people's thumbs and images on their server and displaying them in his gallery with his own ads via a php script..
Here's an example:

All of the pics are hotlinked from my domain, sixtyninegalleries.com.. he's just displaying them in his own gallery with his own ads.
His site has tons and tons of galleries listed, I suggest you guys should look in your referral logs for his domain, and either block it in an htaccess or just turn off hotlinking altogether..
