My blog was hacked a month or so ago. Although I got everything up and running again, I still have an issue I'm trying to sort out. Google has a lot of those hacked pages in cache:
(see the fourth link and onwards). All of those 'queries' start with '?ZXcf'. Right now, all those links (malformed queries?) lead to my blog's home page, but I'd like to make them go to a 404 page if I can. Is this possible?
