Per friends who have done this, you apparently need to explain why and have reasons™. It’s not just a quick “hi forget me” request. All of which I find a bit absurd.
I should have been more clear. You have to give reasons why, as in - if your identity is at risk, legal issues, company concerns..etc. This was the push back my friends and I have joked about (only two so far who have made this request).
The request is not taken at face value, you have to have it approved.
