I believe the main concern about these filters is the proven record that normal internet speeds suffer dramatically! I have heard 87% but even conservative estimates have a speed reduction in the order of 50% or so. This would throw Australia behind in the internet computer age, lets face it the speeds are already pretty poor compared to many overseas developed countries.
And apart from the fact the filters would be a failure! I am sure there must be hundreds if not thousands of new "objectionable" sites popping up daily anyway?! It is a logistical and speed limiting nightmare!
