You're welcome. I have posted your message on the FB page together with your e-mail address. It is probably unlikely that you will get any action until after Christmas.
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 .
