Notes: Autism is uncertain, also, I would put the YouTube one, but my former school's system is even harder to circumvent...* And yes, IRL, I have THE WORST attention span EVER. Also, sry for the long rant in footnotes.
*For context, my former school has no TRUE router blacklists or whitelists** (THANKFULLY) but they use something MUCH worse... GoGuardian... UGH. But there's a way to circumvent it. Even on Chromebooks. All you need to have are "kiosk apps", which run outside of the full chromeOS environment, and thus, don't have extensions. All you have to do is get to Google, and boom. Full Internet. And with our Chromebooks, the only kiosk app was for CollegeBoard (for taking AP's), so we (that is, I was the only user who knew about this. Not even Rob, our tech department team LEADER knew about this... Yeah...) had to go through a VERY convoluted set of redirects to get to Google, which... If you can believe it... Got more complex as CollegeBoard became aware of this, but also had to link their social media accounts, including their YouTube channel.
**If they had these, which tell devices what sites can be accessed (FYI, blacklists allow everything except sites on the list, and whitelists allow only sites on the list), nothing would be able to circumvent them, aside from switching networks entirely.
