The ACMA are underestimating the amount of sites/pages that would need 
to be included on the blacklist if they are to go with what Conroy wants 
(more than just illegal content).

Someone from the department last night commented that international 
filtering examples have shown that URLs to illegal sites change rapidly 
(due to police action, to avoid detection etc) and as such the URLs on 
the blacklist change often. I believe the example they used was around 
1500 actives sites on the list at any one time (I cannot remember which 
country they were referring to).

If X rated material (or even adult content) was included on the list 
that wouldn't be the case. Because it's legal the sites won't be 
changing URLs or running from the law. The amount of sites on the 
blacklist would be considerably higher than just a list with illegal 
sites (where old ones are possibly removed).

What criteria will constitute a success in Tasmania. That I'd love to 
find out.
