There isn't an option to block them, only authorize.
It makes no sense, I'd block 'em.
That site appeared about a month or so ago. I had the pleasure of looking at "Your ads have recently appeared on websites you haven't authorised. To avoid lost revenue, make sure that you authorise any sites where you display ads by visiting your account settings." for about a week before it finally disappeared off the list. Then it appeared again about 5-6 days ago. Again, I have to see that above message.
On a side note: Even if you do authorize it, that ruddy message still stays there. Fecking annoying.
