I've never used glassdoor myself, but don't you need to use your company email while leaving the review to prove you actually work there, so leaving an anonymous review isn't even possible? Why would anybody use glassdoor if that's the case?

I think you have the option of saying that you're a former employee, and in that case you only need to validate an address not one tied to a specific domain.

In any case the idea of a company email is a little hard to define from the perspective of a 3rd party that deals with millions of companies; different TLD's, domains, sub domains etc make it very hard to nail down exactly which pattern is the definition of any given companies real email addresses.

I think that this one is way harder to avoid than you might think, short of having someone else write the review for you (which might not be a bad idea!).

You might be able to get by with something like throwing it through Google Translate to a different language, then back, and then fix only anything that's _unreadably_ awful. Might be too blunt of a tool though.

The other thing I can think to try to do would just be avoid any complete sentences, just give short bulletpoints or something. Resticting the amount of text should make it harder to get anything like a real match.

Yeah it's not easy, having someone else write it like you said is probably the easiest way.

In a few reviews I've left (using different accounts etc for each one to avoid fingerprinting!) I've written the review myself, changed it to a formal register, thesaurus-ed a few words, and also threw in a few red herrings to make which team I was from appear ambiguous (for example, whine about sales tooling/CRM when you're an engineer that has nothing to do with sales).
