Is this censored? There's nothing related to copyright infringement or porn in there. Also, the categories and trending/most-searched selection seems arbitrary. Every country has a different set of data.
I wouldn't be surprised if their result set was filtered on the same rules used for Google Suggest, which do filter out terms presumably linked to controversial file sharing websites (Pirate Bay) and adult entertainment.
I think it's funny that they censor pornstar names. I mean, it makes sense, but it's just funny how google instant quits working after a somewhat generic first name sometimes.
