I tried googling it, but the page for the thread wouldn't open, and so with other similar questions... :/
So the reason is, I want to cut off all contact with this user, but I found out that if you delete and block a contact from your list, your name still shows up in THEIR list, even though your private details don't show, I want to remove my name from their list still. Is there a way to do this?
No, there is no way for you to delete yourself from someone else's contact list. You would need access to their account to do this.
