Obviously, I know its impossible to completely child-proof a PC, but theoretically, what steps would you take? Assume its a laptop with internet access, meaning you’d want local solutions and something like a pi-hole wouldn’t work well.
I would personally assume, you’d want to:
A) discourage internet exploration by offering ready-to-use options for most needs, such as thumbnails/bookmarks for common websites.
B) Implement some sort of blacklist for common or easy-to-stumble-upon negative content. Maybe something as simple as a Ublock filter?
C) Robust monitoring tools, although I have no idea what.
Edit: To be clear, I know education is the number one tool, but let’s say a tech illiterate friend is asking for help. What might you set up for them, or recommend they use - tools to assist in parenting, not replace it.


Blocks are invitations to become a hacker. Teach your kids to trust you and they’ll talk to you about anything they see.
I don’t see that as a bad thing.
Except it makes it that much more enticing to find the forbidden thing. I had open internet access and I definitely wasn’t looking for gore or anything like that. But at school, where the wifi was locked down, that gave me every reason to fuck around with it.
My parents took this approach with the idea that if I’m capable enough to circumvent a barrier, I’m probably capable enough to not need it. It’s an ideal I championed for a long time until I developed enough of a mind to understand that this approach is what gave me the confidence to go out and get molested when I started getting curious about sex.
