I have the turned on the setting “display name on posts: Show a user’s full name on their posts in addition to their @username”.
It works, but not on all users. I have found a user that I can only see his username, not the full name in posts.
Is this a setting that can be overridden by the user?
PS. I want my community to be based on openness/transparency so I don’t like any user to hide his/her name.
