I’m so sorry this happened to you, hazelanibunny! Yes, definitely leave a review to help other HOs. Don’t worry about retribution, if your sit is attractive, there will be other sitters who are interested even if one sitter leaves a bad review.
She didn’t accuse anyone by name. She related her experience. There’s no “accused party” here. No one’s reputation is getting bashed.

You seem to have a different rule for yourself. Why are you allowed to complain about people who aren’t here to defend themselves and tell their side of the story?
