From Mary on DigiActive:
What: a Facebook-based campaign to free the blogger Hossein “Hoder” Derakhshan, who has allegedly been in taken into custody by Iranian authorities on charges of spying for Israel. (There has been no official confirmation of Hoder’s arrest other than an article on the Jahan News site and the fact that he has not updated his blog for 2 weeks.)
Where: On your Facebook profile page
How: There are several ways you can support Hoder. A message from the Facebook group, Free Hossein Derakhshan // Libérez Hossein Derakhshan, asks supporters to do the following:
1. Invite your friend list to join this group
2. Download and Add this picture to your profile picture: http://tinyurl.com/5983v3
3. Tell your friends, family, and colleagues about the situation
4. Write the Canadian Embassy in Iran (address below) notifying them of Hossein’s condition: firstname.lastname@example.org.
You can also get news about Hoder on the Twitter channel twitter.com/freehoder.
Why: Because Hoder’s alleged arrest is illegal and he deserves his freedom.
