Can someone rewind please?
While there has been loose talk from the government about blocking
"inappropriate" content, AFAIK the only black-and-white commitment they
have made is to block (or have blocked) the expressly banned URLs,
listed by ACMA, of which there are on the order of 1000.
This always struck me as leaving wriggle room, so they might have a
baseline that was technically achievable, and leave open to
interpretation just how inappropriate "inappropriate" would be (i.e.
they could fall all the way back to that which is expressly banned).
[In a similar vein, I had the distinct impression at the time that the
government mentioned the blocking of child pornography sites, but that
media reports shifted the language to the fantastically broader realm of
sites containing material deemed inappropriate for children.]
But I might be wrong. Can someone clarify if the government has really
ever declared itself to be up for the open ended caper of tracking and
blocking "inappropriate" content generally?
