If this is a place you dont see yourself using as a reference(or make a burner account), you could help a lot of people who are thinking of applying to said places. I know it could be different from person to person but had i seen a shitty review on the current place im working i never wouldve taken the job or at the very least had a better understanding of what i was walking into. Lots of companies give themselves 5 stars and a great review please be honest and set the record strait to these people.
