Maybe the service leaves the manager anonymous until the review amount crosses a certain threshold... 3 to 4 guys calling him out?

Wouldn’t managers just make a service where they review and score engineers too?
Each engineer has one manager, thus they have one review. The profile doesn't open up until after the engineer worked for several managers and 3 or 4 of them leave bad reviews.
It's fair. But managers are more at risk. Still this process keeps everyone in line. Don't be a jackass is the key metric here.
But seriously: there isn't a way. This is why sites like Glassdoor are garbage and teacher rating sites have ruined careers over minor issues.
That means one person can't run a smear campaign. At least 2 or 3 other people have to agree with you, and if they do then it's legit. The system masks the persons negative reviews until that manager has accumulated greater than 3 or 4.
Three or four negative reviews from people in the company is NOT a minor issue.
