For no known reason, Squidoo.com is blocked. I would urge everyone to go to this form and fill it so we can get it unblocked as soon as possible. As for what to type in the reason for unblock, you could use the following sentence taken from Wikipedia:
Squidoo is a website designed to make it easy for anyone, for free, to set up a single page on a topic he or she knows or cares a lot about. Advertising revenue is shared with these content creators, and some of it is given to charity. Squidoo was launched in October 2005 by Squidoo.com, LLC based in Irvington, New York; the site came out of beta testing in March 2006.
According to the block page URL, categorydescriptionlist = Pornography! I really can’t comment on that. Lets hope it gets unblocked soon!
Update: Still blocked as of this day May 4th 2008.
