Im trying to make a cloud system that can store messages but im worried that someone can modify it, its for my most recent project: T . W. I. T. T. E. R in scratch and i write it like that because scratch doesnt let you write that

There's no way to secure cloud variables from being changed unless you want to make an external server that reads from Scratch's cloud variables and stores the data there. People can use external scripts to change cloud variables, which is why people complain about “hackers” on cloud variable projects.

I would also like to note that if people can freely talk on your project, the Scratch Team may take it down for being a cloud chatroom. Those types of projects aren't allowed because they are not moderated.

@PhiPhenomenon In my proyect persons cant talk whatever they want, they are limitated to a few hundreds words like:“Hello” or “Because” there are no offensive words or something like that. Also if i make every single block in a custom block with a random name will it make harder to “hack” the cloud system?

Anyways i think only a few persons will try the proyect so i think i dont have to worry about “Hackers”, for example my project “Stay in this project the longest you can” havent be hacked even if it have 80+ visits

That still unfortunately isn't allowed.

What if my cloud chat uses a whitelist of acceptable words?

We will be removing all projects we see with cloud-chat functionality, even if they have whitelists.

You are only allowed to have a preset of phrases, like “Hello! How are you?” or “I'm leaving.”

Not really. The way the external scripts work doesn't use any of your code to update the cloud variables. It can directly change them. All they need to know is the encoding.

Or what if it only works with emojis

So now i have another idea, in the project there will be diferent opinions like “Is pineapple on pizza gross?” and then the user replies with emojis:

Totally agree
agree
neutro
disagree
Totally disagree

The users cant post new opinions but can suggest in the comments

thats actually a good project idea as you can't really be limited on the length of cloud variables
