Scratch should make it possible to make projects "unremixable"

Basically, the code is still accessible, but if you're a student accessing a project that was marked by an educator as a “solution project”, a spoiler message appears after clicking See Inside that says:
You are about to view the solution to “Project Name Here”.

If you see it before your educator allows it, the educator will be notified and your grade may be compromised.
Do you wish to continue?

Yes, let me see inside No, take me back

Now a bigger issue is how to prevent guests from viewing such projects.
Have school-private projects?

Any inappropriate messages would be the school's responsibility, not Scratch's.

What if a bunch of scratchers who aren't part of a school sign up as one?

I'm pretty sure the ST would make sure to validate schools who sign up for school accounts.

Do you really think that the ST has the time to go through every school that signs up for an account?

Hi.

I think it should be possible to fulfill your request, wotto.
For instance it seems possible to make a special build of the Scratch 2 offline tool.
Source is available on GitHub: https://github.com/LLK/scratch-flash

In src/UI/parts, you could for example first modify the TopBarPart.as script in order to inactivate the export button:
addChild(exportButton = new Button('Save Project', function():void { app.exportProjectToFile(); }));

If additionally you want to prevent your students from loading the .sb2 file from an other Scratch interpreter, then you might encode all your .sb2 sources with an asymmetric key encryption scheme, hardcoding in some hidden way the q key in the Scratch 2 offline tool, and encoding all your .sb2 sources using your p key. Maybe using the as3crypto library ? Then you just insert a decryption section in the File/Open section of the offline tool, and… that should be it. Btw you might also use a symmetric encryption algorithm. Or some home-made, simple encryption process that makes the .sb2 unreadable (for instance a bit shift on each byte).

For hiding your code, well you might simply force through actionscript, Scratch 2 Offline to use chinese language?
Or change the locale message file for making the code unreadable? (I did it, it works)
Or maybe hide the scripts tab via an update of TabsPart.as:
public function TabsPart(app:Scratch) {
function selectScripts(b:IconButton):void { app.setTab('scripts') }
function selectImages(b:IconButton):void { app.setTab('images') }
function selectSounds(b:IconButton):void { app.setTab('sounds') }

this.app = app;
scriptsTab = makeTab('Scripts', selectScripts);
imagesTab = makeTab('Images', selectImages); // changed to ‘Costumes’ or ‘Scenes’ by refresh()
soundsTab = makeTab('Sounds', selectSounds);
addChild(scriptsTab);
addChild(imagesTab);
addChild(soundsTab);
scriptsTab.turnOn();
}

If your students are smart enough to find back the pieces of your q key, or s key, or home-made encryption algorithm disseminated throughout your .as code, well… I think they should be graduated at once.

Greetz.

Its easy to do. If the email/website has a .edu it is a school.

But that still takes time.

Currently, if you try to enter a fake email which doesn't follow the email syntax, Scratch will say that the email isn't right. The Scratch Team wouldn't have to manually check each email, they could just program a parser, which is easy with regex.

I HIGHLY doubt you're a teacher.

A teacher wouldn't say “sucks” in social media.

I need items for a game I'm working on! If you want to help and be in the credits, you can suggest one in this hyperlink.

There’s no way to stop remixing. I suggest showing it in fullscreen if it’s that bad.

It was on the Wiki, and I never read when it was posted. And it’s a suggestion, not necropost.
Oh wait. The user is no longer active on Scratch anyway.
