Unfortunately I think it's time to spend some money to take the stolen profits back from this guy... But what i would really like to know is how this works for his benefit?!
I understand what you are saying about a spider finding the 302 redirect and on his site... and the spider choosing to drop the original page in favour of his copied version...
But after that happens... what does this guy end up with? Does his page get treated as more relevent for the hijacked pages search terms? or does he inherit the hijacked pages PR?
Logic tells me that if google drops one page in favor of another then it would schedule the new page for indexing and probably leave one of those results you see with no title or description until that new page was fully indexed...
If that is what happens to this guys sites I am struggling to see what his strategy is... as that scenario would not bring him any traffic I dont think.
even if he copied your exact design I cant imagine he would also get your PR... therefore he would need his own existing PR domain to do it from... and even then I doubt he could end up with the same SERP spots the genuine domain had.. unless he has found a loophole in the way Google works...
Is his use of a 302 code significant? will that make google drop the original page and use that pages indexed data in results for his new page maybe? ( btw, does he always copy Exactly the source of the hijacked site to his server or is there any changes he makes to the code?)
If his site is redirecting with a 302 I would have thought that meant the spider would think his site was the original and the hijacked site was the temporary location (or do I have my logic wrong there)
Either this guy has found some loophole or he is isnt getting advantage from what he is doing that i can see.
btw... the site he posted asking for linktrades is offline now for some reason.
Garv... I see the nurses domain he is using with your content is hosted here
Name Server: NS1.BLUEGRAVITY.COM
Name Server: NS2.BLUEGRAVITY.COM
I dont believe Tom and the Bluegravity crew would simply ignore a DMCA complaint... If they do.... forget this guy and find a lawyer to go them.. you will have to lodge a proper DMCA complaint first though... if you have already done that and BlueGravity havent acted.. then go straight to GO and Collect $200... you have an open and shut case for a judge... But i would be shocked if you couldn't pick up the phone and call blue gravity and get some sort of help.. a response at least.
Most hosting companies will act on a DMCA complaint I think... maybe a host company owner can give us some advice on that...... Although I recently found out GoDaddy hosting doesnt repect the digital millenium copyright act anymore... they demand you have paid to register your site as copyright before the theft ocurrs... conveniently they sell just such a service now)
Here is link that a webmaster has put up to help others lodge DMCA complaints... (I cant vouch for the accuracy)
