This is good advice, but in many cases, the number of positive ratings far outnumbers the number of negatives so the negatives may have limited impact.
You absolutely should produce a histogram to see what kinds of ratings you are getting and how many users are producing them. You should also consider implicit feedback. This tends to be much higher value than ratings for two reasons: 1) there is usually 100x more of it 2) you generally care more about what people do than what they say. Implicit feedback is based on what people do and ratings are what they say. Inferring what people will do based on what they say is more difficult than inferring what they will do based on what they do.
