There were a few approches until now, already with low success or technical implications (other sites also blocked, etc.)
The discussion now happend on society level. Any bigger ISP will never offically reject such blocking requests for child pornography in a tv interview as this can hardly hit their image in the public.
The technical questions of the blocking are completly fadet out. They didn't really care anyone. Blocking can and will definitivly not work. Endusers can implement workarrounds in less than a minute. Other questions like, who's maintaining the list etc. are not even discussed.
I'm really concerned about the way that this story will/ can go...
