How is the content of this webpage protected? : <p>I have a little homework webpage, so I am often looking for ideas. I went to Liz's ielts <a href="https://ieltsliz.com/ielts-multiple-choice-listening-turtles/" rel="nofollow noreferrer">page</a>.</p>

<p>Normally, a right click and you can look at the source code, but Liz is smart: if you right click you just get a "Alert content is protected" message.</p>

<p>Very interesting! I've never seen that before. How is that done?</p>
