I keep thinking about this response from a glassdoor employee, and what it implies about their decision making processes:
I stand behind the decision that your name has to be placed on your profile and it cannot be reverted or nullified/anonymized from the platform. I am sorry that we disagree on this issue. [...] This is my final determination. I, as well as multiple members of my team, have reviewed your request several times, and I am considering this matter closed.
