[liberationtech] Tor: Increased Internet blocking in Iran

[Collin Anderson]

Apologies for the extra message, but to add: more recently a 'cyberpolice'
was established that will begin monitoring next week, starting in Tehran and
then moving into other cities.

Sydkazm Hashmabady, Organizing Committee meeting in cyberspace, said:
"Police cyberspace in order to deal with threats in cyberspace and Internet
addiction issues such formed. The police are ready to citizens in cyberspace
and give advice Also ready to invest in the cultural sector is a virtual
space.

I think using China as a frame of reference seems increasingly accurate.
Especially using 'internet addiction' as a premise for monitoring and
filtering against social ills.
