Is there a way to report obvious paid reviews?

There was this horrible movie where all the reviews were either 1-2 stars, or 10 stars. Someone pointed out that all of the 10 star ones were either brand new accounts, or were coming from people who were all giving 10 star reviews to the exact same movies. I checked and sure enough that is what was going on:

In order for the IMDB reviews to be of any value there really needs to be trust in them, but I see no way to report these fraudulent reviews. I can flag a review as "Not Helpful", but people looking at the ratings and not the individual reviews will never know one way or the other whether or not they were ever flagged (most people probably wouldn't realize it even looking at the reviews unless they were already very familiar with IMDB). Is there really no way to to flag these as fraudulent, or am I missing something?

Thanks.
