It doesn't matter where or whom vote. It does count the votes from the IMDB's regular voters for the Ranking. Here, more than 70% votes are probably first time (fans) or non-regular voters. The film wouldn't be listed in Top 250 even if it has 10/10 with more than 100K votes. There is a logic behind IMDB's regular voters. No one knows that.
11,000+ votes for 10/10 rating seems fishy, other ratings are less then 700! Its not just one fanboy. They have forums. All the members are encouraged to give the movie the highest rating.
