If your site is pushing sponsor programs you can contact those sponsors and they may act on your behalf. Worked for me recently when someone was ripping my site and I was having difficulty finding a working email for them. While most of the sponsors said they couldn't help, a few were pro-active and either deleted their accounts outright or sent them a message saying to resolve the matter or face deletion. I got an email from them within 24 hours and my content was removed. (Their response was a variation of 'rogue employee', in this case their brother - or so they claimed.)

Also, while some of the privacy folks do not like having Google track their shit, I have found having analytics lets Google know precisely when your content was added and speeds up their DMCA process if you have to go that route.
