speaking of this, does anyone have the html/images of the iranian block page? I collect them and would really appreciate it if someone was able to send that along. Or does the iranian firewall just drop the connection without the censorship notice?
The goal might not be censorship, even. Iran's most prominent recent actions have been provocative trade threats and hacking a US drone -- and US Presidential candidates have been discussing the possibility of eventually invading Iran. Iran has plenty of paranoia to spare:

I'm guessing that they're dropping connections in part based on that; fear of spies rather than fear of speech. In which case they wouldn't really have any motive for a blockpage, either.
It is clearly population/sentiment control and not 'fear of spies'.
