Go to the reddit homepage. Look at the very top link (that&#x27;s highlighed with an outline). That&#x27;s an ad, but it&#x27;s hosted by reddit and contains no scripts or iframes, in fact doesn&#x27;t even contain offsite images. Its div has the CSS class promotedlink. If you look in the default list used by Adblock Plus <a href="https:&#x2F;&#x2F;easylist-downloads.adblockplus.org&#x2F;easylist.txt" rel="nofollow">https:&#x2F;&#x2F;easylist-downloads.adblockplus.org&#x2F;easylist.txt</a> you will see that it blocks this because it contains the line<p><pre><code>    reddit.com##.promotedlink
</code></pre>
But Adblock Plus actually contains a second list of &quot;Non-intrusive advertising&quot; that actually allows ads on reddit. Many people are very angry about this list because many companies pay to get their ads put on it and allowed.
