How this anti-bot defence works? : <p>I tried loading a few pages from <a href="https://property24.com" rel="nofollow noreferrer">https://property24.com</a> with Selenium &amp; Chrome/Firefox.
I have got instant block after downloading single page.</p>

<p>Now I see this <a href="https://i.stack.imgur.com/vOuIg.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/vOuIg.png" alt="enter image description here"></a>
Any ideas what service they use?</p>
