I'm not speaking with much authority. I'm querying why people are so ... worked up? Over filtering and making sure kids are "safe". Even in the mid nineties this was a massive concern, so it's not new. I've just never found anything that scary, so I'm wondering what people are concerned about when they see 8 yr olds on the net.

Perceived control is a hell of a placebo.

It's not just perceived control - it's the reenforcement. We all speed, but we always speed just a bit over the limit. Raise the limit, people raise their speed.

10 year olds goaded on by friends shouldn't be looking at the kinds of materials that are 18+ on the net today. Heck, most of Reddit isn't appropriate for growing minds.

The comment is phrased as a question, not a recommendation. (Although I could see how a recommendation could be inferred.)

What specific issues do you have with the poster's approach to his kids' internet access?

No specific issues, it's not an issue I've thought about. And however the phrasing, that this is the policy he's using with his own kids has to count as something of a recommendation.
