What about Aria Giovanni? One of the most popular and most searched for adult stars on the entire internet, and certainly more searched for than any other vghd girl - according to google adwords keyword tool.
See this thread.

I'm quite convinced that a great deal of ratings are made without even seeing the trailer, and simply on the basis of a few pictures. That's like rating a movie on the basis of the poster outside the cinema. Then there's multiple account rating to consider as well.
So as far as I'm concerned the ratings are far from valid as an indicator of popularity and even less so as an indicator of performance quality.
