We dont bother spending all that time. Its not worth it. Here is my view to this....if a site is dead ( no traffic ), there are no damages, if a site is active and has traffic , believe me we will know about them. And will file a complaint ;-)....
I think everyone is underestimating the seriousness of damages to copyright and wont want the legal hassles...so most serious business owners in this industry cant afford to risk such mistakes....wont make it. At least in the long run....
