I think the authorities will come to their senses soon (assuming that the story is true, that is). Anyway, I am able to access blogspot sites by using Tor.
The funny thing is, the Boing Boing page contains links to helpful pages that supposedly tell you how to bypass this block, but these pages themselves are from a blogspot site.
BTW, the Torbutton Firefox extension is *way* better than SwitchProxy.
