The people who set up this site are trying to get error code 451 
accepted as a way of telling users the content they are trying to access 
is unavailable for political reasons.  In other words, unavailable 
because government has ordered the ISP to block access to the url in 
question.  They argue that the 403 error code doesn't tell the user why 
the url is unavailable.
