The function User interests when using tags are a great way for a user to have favourite tags at hand in the profile. But there is a problem regarding user integrity that users can see other users that have selected the same tags (interests).
I suggest three more settings to make User interests possible to use with the user integrity in focus (for now we must have it inactivated):

1. main core setting: Activate Show/hide users interests from other users with the same interests
2. default core setting: Show/hide users interests from other users with the same interests
3. user setting: Show/hide my interests from other users with the same interests
