This plugin enables blog owners to allow some shortcodes to be used in comments. You can choose what to allow (i.e. Whitelist some shortcodes). It only affects shortcodes in comments, but not in pages, posts, etc. All shortcodes are default to be disabled.

Surbma

A simple shortcode to display recent comments. You can use it in text widgets or with every shortcode enabled page builder.
The shortcode: 
 [recent-comments] 
 [recent-comments number=”10″ author=”” title=””]
There are seven parameters for this shortcode:
<ol>
<li>author__not_in – Author ID to exclude from the list. Default: NULL to list all comments from all authors.</li>
<li>number – Number of comments to return. Leave blank to return all comments. Default: 5</li>
<li>order – How to sort comments: ‘ASC’ (Ascending – lowest to highest) or ‘DESC’ (Descending – highest to lowest). Default: DESC</li>
<li>author – Do you want to hide the author? Just give an empty parameter: author=””</li>
<li>title – Do you want to hide the title? Just give an empty parameter: title=””</li>
<li>excerpt – Do you want to hide the excerpt? Just give an empty parameter: excerpt=””</li>
<li>morelink – You can specify the text of the more link. Do you want to hide the more link? Just give an empty parameter: morelink=””</li>
</ol>
There is no mandatory parameter, you can use the shortcode as is.
IMPORTANT! This (or any other) shortcode is working only in a widget, if you or the theme has enabled the use of shortcodes in widgets. I’m not giving any description how you can do it, because there are a lot of posts out there. You can do a search for this: wordpress enable shortcodes in widgets
