A year ago Mastodon 4.2 expanded the HTML filter to allow a whole bunch of additional tags... anyone know of any good examples of accounts that are using that bounty of additional formatting options? https://docs.joinmastodon.org/spec/activitypub/#sanitization

Since Mastodon v4.2, the following elements and attributes are supported:

<p>
<span> ( class )
<br>
<a> ( href , rel , class )
<del>
<pre>
<code>
<em>
<strong>
<b>
<i>
<u>
<ul>
<ol> ( start , reversed )
<li> ( value )
<blockquote>
headings will be converted to <strong> and then wrapped in <p>
