I went to a pediatrician near where I lived. Long story short, she was very toxic, making ultimatums and giving what was revealed as dubious practice. I consulted other similar pediatricians, who all gave me radically different answers than hers.

As a result, I chose to write a detailed review explaining why I thought she was unprofessional, citing examples. Of course, my review got nuked.

Same happened with a photo shop that screw up a photo development for some films. I left a factual review, with a sample in pictures. I can see my review with my account, but no one else can.
