Looks like a way to get some extra google traffic. Check the source, it's a frame to your site for browsers that support it, and a bunch of links to his other subdomains in the NOFRAME area.
I'd be pretty pissed if my paysite was opened in a frame like this, since people might bookmark the wrong address, or have extra things like timed consoles flying up at them... put in some frame breaker code, problem solved.
