What good is it to send FIFA traffic to your hosting site? If you get 1 million visitors how many do you think will buy hosting?
Using un-related domains to push people to your site will likely do nothing but tarnish the image of your company and possible irk all mighty google.
I scoop up relevant domains when I find them as we used to have a mini-site marketing idea. However, mini-sites are largely frowned upon by google and other SE's these days, so we've canned that project as well.
