Who's to blame for that, I guess it is not the progressing technology should be blame, instead blames are all to the parents or guardians for failure to do their job in monitoring their kids.
Nonsense. You can't control and monitor kids 24 hours/day 7 days week, that would make you bad parent and kids will probably hate you. You can guide them and teach them what is good and what is bad. It's only up to them if they want to take advice and guidelines or not.
