If your kid can figure out how to install a custom certificate on their device and MITM SSL to evade filters, (a) you never secured the device (b) you already lost long ago and (c) let’s get that kid a job or a scholarship.
What I’m saying is you can set rules, you can try your best, but under no circumstances can you build an impenetrable wall for determined kids. Things like this header solution or better controls on the end device would make things safe for the vast majority of kids. So don’t ruin the internet for adults because of a handful of unruly kids who are going to get in trouble no matter what.
1-2 years later, the teacher at school showed us how to program the turtle program, and I got it stuck in an infinite loop in 10 minutes. The teacher started swearing "Your chair is smashing the ethernet cable. The program is good and you fucked it up."
Around that time, I remember going to a barber shop for a haircut and stealing his nude/porn magazines. Even younger, I used to sneak up to my uncle's bedroom where he hid alcohol, and drunk half a bottle of whisky in an hour, and getting knocked out every time.
I used to get involved in fights all the time, since 8 years old, and my favorite activity at that age, was to climb to roofs of abandoned houses at night, and wander around inside of them.
My parents regularly tried to talk some sense into me, and I was beaten up by my father for all the stuff I did.
When I was sixteen, I managed to steal a car by myself, I drove it around for 1-2 hours and I didn't know how to drive, I figured it out at that moment. After that I returned the car where it was at the start, I didn't do anything with it, but when driving it I managed to flat the tire somehow.
When I was at the university, at some point around 20 years old, I downloaded Kevin Mitnick's book from torrents, I read it, and I got inspired to phone to my university, pretend I am a professor and I want pass a student (me) for 2 courses. I passed the courses without even taking the exam.
It was around that time, a friend of mine, while he was playing the guitar at his house, he looked at me at the eyes and said dead serious: "Man, if you go on like this, you will end up in jail." It was actually earth shattering! First time someone talk some sense into me. I thought, this cannot continue, he is right.
It's probably worth noting that if teens can not view porn, they will likely produce porn making an entirely new tax free underground market on Tor or other networks.
This is just for keeping small children out. Nobody in the history or future of earth have ever or will ever locked teens out of a thing. Archive this comment so we can review it at a later time.
An aspiring teen could just have sex with another aspiring teen...
You won't stop teenagers from finding a way to be teenagers. Part of being a teenager is learning how to subvert the rules set by adults to fulfil one's hormonal imperative.
Who cares? Why is this an issue? An aspiring teen can (and will) do many things their parents don't know about. It's part of growing up. Making air tight surveillance systems to prevent teens from talking to friends or looking at boobies is many a bridge too far.
If circumventing a measure requires setting up a RPi and modifying headers, I would call it widely successful, that would be less than a thousandth of kids.
Just like how teens are already bypassing age-gates? The point is to make it the responsibility of the parents and not of the government.
An aspiring teen could set up an RPi that modifies headers for all traffic on the network that the parental units never even know about. I'd venture there would be plenty of YT, TikTok, Discord threads, etc that would provide a step-by-step set of instructions to do it. Probably just point to an image to download to copy to your SD and voila.
