I said try doing it using Tor with JavaScript disabled, which is the safe way to use the Tor Browser. I said nothing about a VPN. A VPN will not save you from leaking identifying information from your device and browser, while the Tor Browser at least attempts to minimize such identifying information.
> "A VPN will not save you from leaking identifying information"
What identifying information? There is no identifying information other than IP address, email and anything else you volunteered when signing up.
Remember the context here. It's "toy company" grumpy about a negative review, and wanting Glassdoor to hand over what they know.
Have a guess what Glassdoor will hand over? Email address, IP, and whatever else you willingly gave to Glassdoor. They won't have any other information from "javascript" or whatever you are claiming is leaked from normal web browsers.
A company's pettiness can know no bounds, and a toy company is just as capable of hiring firms that specialize in de-anonymization as any other company is. The company itself also has billions of dollars of revenue and can hire experts in the field themselves.
Companies do not just log IP addresses and email addresses, there are billion dollar ad networks that have refined the game of tracking users across browsers and devices, and they certainly do not rely on just IP and email addresses.
Many companies keep extensive logs of analytics data that their customers generate that amount to much more than IP and email addresses. If a company is motivated enough, there really isn't anything stopping them from cross referencing their own logs and employees/users' identifying data with whatever Glassdoor, and any of its partner services they've integrated with, collected from their users.
And it isn't just JavaScript that leaks identifying information, most browsers do it by default. JavaScript just makes it stupidly convenient, more accurate and opens the door for novel methods for collecting identifying information.
