Glassdoor provides the email `ilikebigbutts@gmail.com`, Google only have VPN/Public WiFi IPs for that account because I'm not an idiot who put my real details into the Google Account.
Not sure I see the problem. They gonna subpoena Starbucks to get the (now probably long deleted) security footage for the time the negative review was posted?
Google, Microsoft, etc make you provide a phone number to create an account, at least when you do it through Tor.
It's annoyingly hard to create a truly anonymous email account these days. Even more privacy-respecting providers like ProtonMail make you verify your account using a phone number or email address when signing up through Tor (though at least with ProtonMail they claim to not associate that information with your account, and you can bypass verification by upgrading to a paid account via a Bitcoin payment).
