It seems like the thread is split between those who value privacy more than preventing child abuse and people who don't believe child abuse and crime in general can actually (gasp) motivate lawmakers to pass laws. Actually, the view of those lawmakers in this thread seems to be some sort of caricature of self-interested future despots, as if most of commenters here are not living in democracies. It would be astonishing if it was not routine on HN... Sure maybe the moral tradeoff is worth it and privacy is top priority. Then I'd recommend to focus on all other areas of life that violate privacy first. Ban airport security, CCTVs etc. After that feel free to move on to banning measures that protect victims, who unlike most of you grown-up functioning adults, can't even stand up for themselves. And address the gravity of that tradeoff, or you're just making nonces out of yourselves.
