Let me see if I'm understanding this correctly...
You own Site A which is at www.example.com and links out to sites you approve in a format like www.example.com/index.php?q=approvedurl
Someone has created a link using your domain but appending their own, non-approved site to it like www.example.com/index.php?q=unapprovedurl
How do you maintain your approved links? Surely you should be able to match q= against your approved list and if it's not there, redirect it or 404 error it? That would make the bad site's efforts null and void.
Or am I misunderstanding the problem?
