Documentation doesn't give enough info on hide_activity_from_users

[TheoStefou]

Looking at this: http://docs.ckan.org/en/latest/maintaining/configuration.html#ckan-hide-activity-from-users

I can't really understand what this field is used for, or rather, what kind of values it receives. I would like to hide all kind of activity from not logged in users, because it compromises the names of the registered users, even if a dataset is public.
Therefore: In order to view the activity stream, a user must be logged in.

Is ckan.hide_activity_from_user the configuration option for this? Is there some keyword (like sysadmin) that refers to "not logged in users"? For example, something like: ckan.hide_activity_from_user = unauthenticated

@TheoStefou @amercader , I did investigation on this issue and found that if ckan.hide_activity_from_user = "user" , then the user will not be able to see his own activities in activity stream. The activity stream is hidden for user itself.
