@SteveEisenberg, @AnotherCat,
I did indeed understand that it isn't permanently banned.
That is why I didn't mention the ban at all, I only made reference to the filter.
Reminds me of that stupid app we discussed a while back,

except government mandated.
Why the ____ is there a "Classification Office", and why are they telling people what books they can buy at what age?
Isn't this a matter of How To Raise Your Children?
If people want to know which books are appropriate for which ages, go make some community-maintained non-profit non-gov't group to give ratings.
