Sorry, I am the author: that block was just temporary and affected ALL traffic to that URL while I updated the post. The block was not targeted at anyone in particular. I never intended for that post to reach as many people as it did. :/ I have a very small audience of people who follow my writing, so it was kind of devastating to see comments here likening me and people like me to "a group that goes around burning libraries." Cheers to everyone who kept it civil.

no probs, site is back up again :)

Thanks for understanding. I never implement blocks on my site lightly.
