It's not stable enough, by the look of it, to be used to hold something while it is worked on, i.e. like a vice, so I reckon it is for decorative purposes, maybe in it's own right, or to hold something for display. But hey, what do I know?
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.
