Is anyone else seeing the ads on this page http://www.imdb.com/title/tt0822854/ (possibly others) under the title "People Viewing This Page May Also Be Interested In These Sponsored Links". The links are to googlesyndication.com and aren't nofollowed. While they disclose that they're sponsored links I'm not seeing a snipped saying "ads by google" or similar... is this regular practice?

The ads are displayed using scripts/iframes, so they're not very accessible to the crawlers. Premium publishers like IMDB can customize the ad formats and change/remove the disclosure.
