We at ReviewInc feel that it is very important for a review site to have this functionality. Even better, we feel that there should not even be a filter, and let readers use their own best judgment when reading reviews.
For example, instead of relegating all the filtered reviews to a no man’s land (essentially where all reviews go to die), perhaps leaving all the reviews on one page, but marking suspicious reviews with some sort of flag that readers can then hover over or click with their mouse to see the reasons why this review is particularly suspicious. Or, even making the background of the reviews a certain color that determines their degree of reliability with a key in the corner that shows what each color level represents. (E.g. blue: reliable, yellow: semi-reliable, red: unreliable).
What do you think? Do you think that review sites should have filters? If so, to what extent do you think these filters should go to in order to capture spam-like reviews? Let us know in the comments below!
UPDATE 11/13/13 10:40 AM PST: It has come to our attention that Yelp has now changed their filtering system from ‘Filtered Reviews’ to ‘Recommended/Not Recommended Reviews’. Per Yelp:
What Are Recommended Reviews?
We get millions of reviews from our users, so we use automated software to recommend the ones that are most helpful for the Yelp community. The software looks at dozens of different signals, including various measures of quality, reliability, and activity on Yelp. The process has nothing to do with whether a business advertises on Yelp or not. The reviews that currently don’t make the cut are listed below and are not factored into this business’s overall star rating. Learn more here.
