I’ve taken a look at their (just today) updated T’s and C’s and they seem to be groovier than before, thus the interesting section (5v) reads:

“Prohibited Uses. You shall not, and shall not authorize or encourage any third party to (v) display any Ad(s), Link(s), or Referral Button(s) on any error page, on any registration or “thank you” page (e.g., a page that thanks a user after he/she has registered with the applicable Web site), on any chat page, in any email, or on any Web page or any Web site that contains any pornographic, hate-related, violent, or illegal content;”

…so I think search results are ok, but avoid user admin pages.
