User reviews sorted by prolific reviewer

It seems to be a bug regarding how user reviews are sorted on default. It used to be sorted by helpful, but at the moment it’s prolific reviewers. Is IMDB aware of this issue, or have they actually changed it permanently? 

In that case, I really hope they’ll consider changing it back. These prolific reviewers often have a completely different view than the average viewer, I want the general consensus, not some negative prick’s opinion with 1-star reviews on every single movie/episode. 

I think it’s a shame that the first review the audience is going to see is a biased opinion, just because he/she have been active on IMDB for years. Thoughts?
