We know that Yuku uses some kind of intermediary script for all outbound links, apparently to track eyes and where they're going to -- the NoScript add-on fore Firefox eliminates that, though. You shouldn't be seeing ads of any sort, so you shouldn't be getting any links off of those. Can you check the console and see what it says? Maybe the URL, if it's listed there, will clue us in.
