I'm a former teacher. Here's why it won't work.
Not all parents care, some parents don't care at all. I saw kids aged about 10 with iPhones and access to the internet. By the time they were 15 I imagine they had seen everything there was to see.
Now, just because your child has their phone locked down doesn't mean that their friends' phones aren't. All you need is one phone in a friendship group with access to the net and your child will be able to view everything.
When I was a kid, you had to get hold of dodgy top shelf magazines or oogle at underwear in a clothes catalogue. Nowadays, kids can view more porn in 10 minutes than most pre-internet people would see in a lifetime.
