I question the accuracy of the current '8.4' user-rating for this truly awful movie!

Rating: 1/10 (1 June 2014)

This review is aimed at the organizers, supervisors, or leaders of this website.
I take IMDb.com very seriously and respectfully use it often as a reference point when considering the purchase of any film to add to my private blu-ray collection.
Additionally, I am careful to rate a particular film 'according to the guidelines outlined' and DO NOT seek to covertly abuse the site by voting more than once per film, using multiple email addresses, for example!
I would like to know how 'The Wolf of Wall Street' has received a current rating of '8.4' when, as you scroll through all the user-reviews, there are very, very few who have rated this movie well at all!
I suggest that perhaps there has been some 'deliberate inflation' of the current rating by some users who have wanted to see this movie promoted much more than it deserves.
I am therefore dismayed that this might be the case, since it calls into question the accuracy of this entire rating system here, with the exception of Metascore.
There is not one of my large group of movie-buff friends here in New Zealand (who all use this website) who have rated this rotten movie above 3.0!
I do not know how I can get a response to my query from the key people it is aimed at.
