The secret articles option (see POST) also adds direct protection to your blog content, and you can individually choose what posts you'd like to add more privacy.
Also if you need to block someone, go to their profile, and click the plus+ icon under their picture/avatar. Here you will find the block button. Your blacklist is to be modified in your settings, under 'friends'.
