+
+	<p>
+		Hotlinking protection has been enabled for this file. This happens when
+		a file is downloaded many times outside of our file viewer page (this
+		page). Usually this means people are using download managers like
+		JDownloader 2, Aria2 or wget. Using a download manager circumvents
+		pixeldrain's advertisements and we lose money because of it. More
+		information about this protection mechanism can be found on <a
+		href="/#hotlinking">the home page</a>.

+		This warning disappears when the you are a
+		<a href="https://www.patreon.com/join/pixeldrain/checkout?rid=5291427&cadence=12" target="_blank">Patreon supporter</a>,
+		or when the uploader of the file enables
+		<a href="/user/subscription">bandwidth sharing</a> on their Pro account
+		(and their data cap has not been used up). Using a download manager with
+		a Pro account is allowed, it will not trigger this warning for other
+		files.

+		You will have to complete a CAPTCHA test to prove that you're not a
