I congratulate you and applaud you for being excited but normally you want to update the same thread each time. It still puts it on top and it's much simpler to follow.
When you block a person, they can no longer invite you to a private message or post to your profile wall. Replies and comments they make will be collapsed/hidden by default. Finally, you'll never receive email notifications about content they create or likes they designate for your content.
Note: if you proceed, you will no longer be following .
