Should I leave a Glassdoor review for my old company?

I left a job at a super small company of 4 employees about 4 months ago. On Glassdoor, the company has multiple 5 star reviews and this always bothered me because it’s totally not a 5 star company.

I realize how important these reviews are to job seekers. Would it be in bad taste leaving an honest review? I’m sure the owners will know it’s me who wrote it.
