How to make an anti-copy and paste system

Hey, devforum!
I am looking on how to make an anti-copy and paste system through a textbox as It’s for an application system.

Any ideas?

you can probably go 2 ways with that system, it is either

  1. Detect when the player starts typing and when they end (I’m assuming the “end” is an enter Gui button) you would then check the time between start typing and end typing, if time is too short then warn them to not copy and paste.

Pros: Works for an impatient person
Cons: someone could copy and paste it and just wait, then they would press the enter button

  1. Detect when the player starts typing and if it reaches over the max word limit in the text you would then warn them

Pros: a more easy way to do an anti copy pasting
Cons: might be a problem for someone who is very fast at typing

those are the things i can think of for anti copy pasting system
