If you would take a moment to look at the stickied thread, you'll notice that in pointing out problems (as opposed to abuse) it is acceptable to post the specific URL and the category, along with a description on why you feel this is a quality issue (dead site, mirror, redirect, etc).
Sending a private message or an e-mail does not guarantee that it will get the attention that it deserves.
I would encourage you to go to the sticky thread, and post the details there. Since the editors who handle those complaints tend to note when specific postings have been handled, you'll get to see if there is any progress on your report.
This may seem bureaucratic, and perhaps it is, but it is the best way of getting the correct level of attention in the least amount of time.
