I had an email about this today. As far as I can tell, it's protesting about online censorship/filters/porn blocking. But neither the name nor the site content make that immediately obvious, which makes me suspect it will be deeply ineffective. Needs a rethink?
I think it's very funny... unfortunately I agree, it assumes some knowledge of the subject before visiting, which isn't a great starting point for a protest.
It's not really the start of the protest, ORG have been doing some great stuff recently with Blocked.org.uk (which is where the data for this campaign comes from)
