An accidental “bug” or data breach could cause these names to become public. Given today’s atmosphere of “Oopsie daisies” and hacks that happen with upsetting frequency, this is a very real thing to be concerned about.
The fact alone that they were storing your name in the first place means that was always possible. Frankly, this isn’t anything to be concerned about anymore than being concerned about trusting literally any private business that doesn’t publicly document their data retention practices and also subject themselves to routine audits. You should be concerned about that though by the way. But my advice is to not wait around for it to become obvious.
They weren't storing your name in the first place; they've acquired a new service 'blowfish' for which an account is automatically created for you if you currently or in the past have used glassdoor. Blowfish demands a real name to be used at all. (including to delete your account)
Ontop of this, after linking the two services on your behalf; glassdoor will now automatically populate your real name and any other information they can gleam from blowfish, your resumes, and any other sources they can find, regardless of whether the information is correct (users have reported lots of incorrect changes). This is new.
It could be hacked, or law enforcement could subpoena the data. Neither are even improbable events nowadays.
Sure, the headline doesn’t quite communicate every possibility or the complete spectrum of dangers, but that’s not the job of a headline. The job of a headline is to get you to click the link.
I was thinking about how this would happen and I remembered when signing up for services using Google login, I’d always get a list of information the website would have access to, including the name listed under the Google account. When I didn’t consent to that, I went back.
Now, is there a line somewhere between strictly getting a user’s consent and the user having an expectation of privacy? Yes, and they may have landed on the wrong side of it.
Suffice it to say, this is one of the reasons I prefer to sign up with an email address.
