	<p>
		Pixeldrain's free tier is supported by advertisements. There's only so
		much that you can do with the budget those ads provide (spoiler: it's
		not a lot). {formatDataVolume(limits.transfer_limit, 3)} per week is
		about the most I can give away for free, and according to our records
		you have already downloaded
		{formatDataVolume(limits.transfer_limit_used, 3)}.
	</p>
	<p>
		It's not that I want to withold this file from you, it's just that I
		don't want pixeldrain to fall into bankruptcy like so many of the
		websites that came before me. So if you really want this file you have a
		few options:
	</p>
	<ul>
		<li>
			Come back next week when your free transfer limit resets
		</li>
		<li>
			Download the file at a rate of {file.download_speed_limit/(1<<10)}
			kiB/s. This will take at least
			{formatDuration((file.size/file.download_speed_limit)*1000)}
		</li>
		<li>
			<a href="https://www.patreon.com/join/pixeldrain" target="_blank" class="button button_highlight">
				<i class="icon">bolt</i> Support Pixeldrain on Patreon
			</a>
			and earn my eternal gratitude
			{#if !window.user_authenticated}
				(you will need a <a href="/register">pixeldrain account</a> to
				receive the benefits)
			{/if}
		</li>
	</ul>
