Some commentors try to abuse the WordPress Comment’s built in URL feature by submitting advertising, spam, or otherwise unwanted links.
Avoid Linkback Abuse tries to prevent this by providing two different modes of operation:
<ul>
<li>Strip all anchors from comment author’s names as they appear 
 in the comments list at the end of posts (always on when 
 the plugin is activated).
<ul>
<li>In addition to the above, this mode will remove 
entirely the ability for commentors to leave a URL. 
Assuming you’re using the default WP Comments plugin 
without any additional comment-modifying plugins, this 
mode still allows commentors to leave their name and email.</li>
</ul>
</li>
</ul>

Avoid Linkback Abuse (ALA)

Remove the URL field from the comments form to prevent linkback spam.

The plugin restores the <code>Title</code> field (that was removed from WordPress 4.2) in the insert link popup box and adds a new <code>Add rel="nofollow" to link</code> checkbox to it.
Gutengerg (Block Editor) Note: At the moment it’s not possible to add the functionality to Gutenberg, it’s a different system from the classic editor and it does not have a hook/filter which allows adding custom settings. As soon as it becomes possible to add the functionality to Gutenberg we will update the plugin.

Title and Nofollow For Links (Classic Editor)

I just installed this on WP 4.9, and it works like a charm. I ended up adding HTML Class manipulation as well, by coping the code in the JS file that added the title field.

Works Well

works with wp 5.2.1

Helpful tool

The plugin adds a title and a rel="nofollow" checkbox to the insert link popup box. Only for Classic Editor, NOT Block Editor.
