My biggest disappointment is that this is still a going concern.

Echoing others, i agree and appreciate that the intent is mostly good, but the facts over and over again say this will not work.

ISP's are saying it won't work.
ICT professionals are saying it won't work. Tech savvy end users are saying it won't work.
You're own studies so far have turned up poor results.
What will it take to stop the government pressing ahead with what is essentially a desperate attempt to waste a lot of money, time and effort achieving nothing?

I would love for my son to not see inappropriate content.
That is why he is supervised by a parent whilst online.

Nothing you can do will beat this. Worse still, a filter will instill a false sense of security.

Think ahead and picture the news headlines "12 year old defeats government filter, sees porn".

This project is doomed to fail, the less time, effort and money put into failing the better.
