Would you link with a site which has a paragraph of virtually hidden text at the bottom of the homepage? It's not exactly white text on white background, but it's pretty close. You actually have to highlight the text with your mouse to read it. Can your site be penalized for linking to such a site?
Below is the site I'm referring to:

www(dot)4mysales(dot)com

After navigating the site I also noticed that when you click on the "Home" link on the nav bar to return to the home page, you're returned to 4mysales(dot)com/index.php which doesn't have the nearly hidden text.

By the way, i wouldn't link to this site anyway because I can't seem to navigate to the recip links pages from the homepage, but I am curious about the hidden text issue.

Thanks
