Just FYI we heard from our forum host that they will be doing maintenance tomorrow from 9 am to noon; Eastern time. The forums may be down periodically during maintenance.
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 .
