The proposed intention of the bill is acceptable - namely, protecting children from pornography. However, the methods aren't thought out well enough. It's not enough that the list of opt-outs is basically a hall-of-shame in and of itself and can lead to serious blackmailing cases (after all, if you're the employee who handles this list, and you see a celebrity or politician on the list, it's easy to give in to temptation), but any idiot who leaks such a list can cause perhaps unrepairable harm to the lives of thousands.
The second, and more serious issue: define "pornography" for me. How exactly do you draw the line between porn and nude art and/or nudism? Blocking the entire domain of, let's say, deviantart is, as a proverb in my language says, "throwing the baby out with the bathwater". Not to mention that in a country of ~60 million, you're guaranteed to piss off someone who has the programming abilities to replace any government website with the most revulsive porn imaginable.
