Detect player writing mistakes?

Im making a 'hack gui' to my game. Players will buy a gamepass, and player with this gamepass will be able to do cool things with this gui (Like turn on fire brigade alarm or change TV image). But im trying to make script that detects if player made a mistake when writing. Then a message will be sent to Police that somebody is trying to hack.

So im trying to make script that detects writing mistakes by player. I would be grateful if somebody could write answer to this question (sorry for my bad english if it is) and also if this is impossible then sorry.

Script (StarterGui button called 'Activate')

            else

if LineScript.Text == "" then
    script.Parent.Parent.Alarm:Play()
    Output.Text = "Error"
    ErrorCounter = ErrorCounter + 1
    if ErrorCounter == 4 then
        script.Parent.Parent.Detected:Play()
        script.Parent.Parent.Alarm:Stop()
        script.Parent.Parent.Tutorial.Visible = false
        script.Parent.Parent.Activate.Visible = false
        Output.Text = "Police have detected you!"
    else
        if ErrorCounter ~= 4 then
    wait(0.5)
    script.Parent.Parent.Alarm:Stop()
    Output.Text = ""
    end
    end
    end
    end
end

end)

Thank you
