Almost everything is a webpage these days. Or a youtube video

They are enabled - the kids have found bypasses. Turning on the hotspot and then using their school device for instance

But not my kids phone that they turned the hotspot on before then. even if I take it their school device can be got from the backpack

I managed to do this once on mbin - but I have no clue how. This is a commonly requested feature.

Depends - what don't you like about your current instance? The ui will be different on each but that isn't good or bad so much as what you like. (No project has a real ui designer)

It only takes one kid to figure out the bypass and it spreads all the kids. Some of those kids are talking to kids going to other schools.

every week my kids hear about a new game the school isn't blocking while they are in class. Sometimes the teachers catch them, but kids are good at hiding what they are doing - and switching to what they should do when the teacher comes near.

I can't - teachers give them homework that must be done on the device all the time.

Every week my kid hears about another game (not boobs) that the school didn't block and thus they can play when the teacher isn't looking. There are also a lot of non educational youtube videos they can watch, but since some of their real educational videos are on youtube they don't block most. (Again youtube will block boobs - but that is not all I'm worried about)

They are only easy to setup if you don't care about getting them right. Either you block a lot of useful content (only approved, audited things allowed), or you block only things that are known evil (that is you audited it). Either way the vast majority of the internet is not audited and we have no idea which of that is good vs evil. (nevermind trying to get a consistent definition of good/evil). The name "onlyfans" makes me think of sports fans and thus something I'd allow kids to access - of course I know better, I'll be there is someone out there who would be setting up the firewall who doesn't know it is in fact adult content.

Age verification needs to be done by someone (probably a government agency, though it need not be) who has verified age. That someone needs to be legally liable (and able to enforce) the tracking rules for anyone who uses their system to verify age. You want to verify someone's age with me, first you need to prove you are following our privacy rules - including our regular random audits.

It needs a better cryptologist than me to get the details of the above system right.

Of course if even if you have the above I'm not sure how you will get anyone to use it. Perhaps we can have schools put a hard block on any system that doesn't follow the above system, but the vast majority of the web isn't going to opt-in. Note in particular this includes a lot of the useful sites I as a parent want my kids to access so it won't help me as a parent.

As a voters you don't get much a choice. In any voting system there is a case where all your choices are for something you are a hard no on.
