Not trying to dog on other parents, but just like when I was growing up a lot of parents either didn't know/didn't care what their kids were watching on TV, and didn't make a lot of effort to control it. Many parents now are sadly similar in not paying attention to their kids' internet habits.

You're being a good parent. I don't know why other people struggle with this idea. In my opinion, you should just be proud of yourself and disappointed in other parents who don't take the same measures.

I will say those other parents make it difficult, though. My sister had to drop a lot of her parental controls eventually because her kids would go to friends' houses with unrestricted internet access, and you just can't control that. Even if you are involved with what your kids watch at home, once they are out of your eyesight and with other people, they can get access. Anyway, denying them access was causing more fights between her and her kids than it was worth. They saw that other kids had unrestricted access, and they wanted that, too. On the plus side, they were already 14 by this time, but still, it became a huge headache because other parents didn't care.

Anyway once again, good on you, mate. Keep being a thoughtful and involved parent, we need more of y'all.
