How to remove the OneBox site-icon from appearing in RSS feeds?

Product Support

Discourse is putting the Onebox favicon as the featured image or your RSS reader is?

Because checking the XML I don’t see Discourse doing this:

<?xml version="1.0" encoding="UTF-8" ?>
<rss version="2.0" xmlns:atom="http://www.w3.org/2005/Atom" xmlns:dc="http://purl.org/dc/elements/1.1/">

    <description>When dropping a link with OneBox, you get the site icon there at the top, and then you get the featured image. See the example below.

Is there a way to yank out the site icon? Not with css tricks.

The issue, when using RSS feeds, it&#39;s pulling in the site icon as the RSS feed thumbnail, instead of the featured image that you would expect. Example [here](https://ibb.co/7ptV8wN) *(I couldn’t upload an image for some reason)*. I don’t mind the site icon being there, but some feed readers, tools, are pulling the first image and using it. Not sure how to get around this.

Oh I see, so the problem is that some RSS readers will pull whatever image they found and use it as a " featured image".

I don’t see us having to parse → filter → serialize posts on every RSS request by default, but this is something you could do in a custom plugin if you own the instance that you care most about.
