A few years ago the Australian government spent an enormous amount of money on a proposed firewall to protect the children. After years of development they were ready to pilot test their white elephant, and discovered that, on average, the Australian 12 year old could bypass it in ten minutes.
It’s unlikely that the government could even enforce an obstacle as robust as the “are you 18+” checkbox that porn sites opt in to. This new law will not have any influence on under 16s online presence.
Theres a scale of influence, with a big difference between foolproof and entirely unenforceable.
In this case, it’s effectively unenforceable, so what’s the point in wasting time and effort drafting something that won’t actually make any difference?
