Yahoo's excellent photo sharing site Flickr is banned and blocked by the United Arab Emirates.
The blocking page reads:
We apologize the site you are attempting to visit has been blocked due to its content being inconsistent with the religious, cultural, political and moral values of the United Arab Emirates.
If you think this site should not be blocked, please visit the Feedback Form available on our website.
Update: Flickr folk tell me this is old, old news... but sometimes old news becomes new again! Er. That's my story and I'm sticking to it.
P.S. YouTube isn't banned.
