Somebody REALLY wanted to hide that!!!!! After looking at it, I can see why...
Basically, they are checking if you have removed their footer links, and their footer links are all site-wide links back to spammy-looking URl's.
In short, do not use this theme. I would not trust any theme from that site. That's the problem with a lot of "free" themes from sites outside of here - there's a whole lot of catches built into them.
Do a search for a theme on here, and you won't have to worry about having that sort of #%^& added to yor site without your permission.
