Question of Loshon Horo belong to your LOR, online reviews are known to be subjective, anonymous, and suspect of being written by a competitor or best friend of the business owner. One bad review doesnt mean anything, 1000 absolutely do. A good manager reads the reviews and responds to the criticism with a thank you for the tip off, it wont happen again!! Any business owner will tell you that no feedback is worse than bad feedback. I think its all about how you present the (bad) facts. I once gave a scathing review on a kosher restaurant but I sprinkled it with deserved compliments. The manager immediately answered me online that they had a staff meeting that very night to discuss my review and changes were made and thank you for bringing these problems to their attention. The quiet unhappy customers arent helping.
