I imagine this won't be a popular opinion, but I don't see why it is necessary for this site to populate the list using javascript when server-side scripting would suffice.

Maybe they're trying to fool search bots so their site won't get delisted? I'm fairly sure Google at least has a bot built on Chrome (or rather Chrome was built around their search bot) that executes JS just fine.

Unfortunately, all it does is make a site that doesn't degrade well with scripting turned off.
