Consider yourself terrorised
Before you've even read this sentence, your browser has downloaded ISIS propaganda in the background.

... no, not really.

But it easily could have.


If you inspect this page, you'll see the following in the document header

<!--
<link rel="preload" href="https://clarionproject.org/factsheets-files/islamic-state-magazine-dabiq-fifteen-breaking-the-cross.pdf" as="fetch" crossorigin>
<link rel="preload" href="https://pbs.twimg.com/media/DzgmCSjXQAAF33w.jpg" as="image" crossorigin>
-->

If the top and bottom lines were removed, your browser would have downloaded the linked ISIS propaganda in the form of a PDF and an image.

To your computer, or anyone monitoring your traffic, this is ostensibly the same as you "manually" (willfully) downloading the same resource.

For more information, see this MDN-page.

Why?

This dumb page was created to demonstrate just how ineffective, abusable and downright stupid this new UK law is, which makes viewing terrorist propaganda even once an offence punishable by a prison sentence of up to 15 years.

Though the "reasonable excuse"-defense exists, it draws arbitrary boundarys for people's freedom to access information.
