There are a bunch of authorities that proof you're a human already. They give you passport and the like. There is nothing prohibiting them from giving you a verifiable credential in addition of a passport.
Also, there are services that proof your humanity all over the internet. Letting them give out verifiable credentials and asking Glassdoor to accept them as trusted credential issuer is the easy part here.
Glassdoor can either check the signature of such a credential or, in the ZKP case, you proof them that you have such a credential without revealing it.

Except they don't do that today, at least in Glassdoor's biggest market (the US). And anyway, all you prove with a credential is that the person is holding a valid credential. You have no idea if it was stolen.
If you used social security numbers for this, for example, a single person could have posted millions of reviews on Glassdoor.

Which ones? The only services that do this are the government and credit bureaus, so the digital services all have to tie in to one of those things. That means that someone is getting your real identity, which doesn't prevent the type of subpoena we're talking about in this case.
And on top of that, those identity checks can be anywhere from $1 to $20. There's no way Glassdoor would survive that.
