I hope you read my post to your previous comment. The best thing to do in this situation is to schedule them, even if just for 5 minutes in the future, and you'll be able to do a page at a time.
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 .
