			Hotlink protection enabled
		</h1>
		<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 that. More
			information about this protection mechanism can be found on <a
			href="/#hotlinking">the home page</a>.

		<h1>

			Download limit reached

		<p>
			You have reached your download limit for today. Without a pixeldrain
			account you are limited to downloading {limits.download_limit} files
			or {formatDataVolume(limits.transfer_limit, 3)} per 48 hours. This limit
			is counted per IP address, so if you're on a shared network it's
			possible that others have also contributed to this limit.
		</p>
		<p>
			In the last 24 hours you have downloaded
			{limits.download_limit_used} files and used
			{formatDataVolume(limits.transfer_limit_used, 3)} bandwidth.

		(and their data cap has not been used up). Using a download manager with
