Hmmm... yes... These secret search links and pages make my head sometimes very hot..and mad also ... sometimes I am also under great pressure and I get a lot of these links, now there is silence. But like they say silence before the storm...we see.
I try be ready when I see this links more.
One thing I recommend everyone to do is change their codes every one and two months also. ( Sometimes they wait a few months before they make attacks, so this codes changes also gives you the opportunity to change the code before they can do something on your pages.
