For those that would like to add security to their profile I suggest the following:

• From your username drop down menu select Manage Followers
• Select Privacy Settings
• Choose one of the following
• Profile is open for registered users only (this will make sure no guests can see your profile)
• Profile is open for (approved) followers only (except admins) (This makes your profile private from anyone but Admin and your followers)
• Click save and you're done
