When I post anything on my page profile, photo and text, depend by the privacy settings the post stay on my page or it's going to photo album. When privacy setting is set to "only friends" the post is going to photo album; when is set to "everyone" the post is freeze to my page. What can I do to make post freeze on my page profile different of my privacy settings?

Second one, it's when I like or comment to an user profile his post start to show to my profile too. How can I set the website to not show my activity to others user profile to my page?
