Whereas the built in moderation just looks for keywords wherever they appear in the comments, Better Moderation allows you to define if it should just be the username, url, email, comment, ip, useragent or all of them. 
It also allows you to define if when looking for “word” whether you should match “WordPress”. 
Finally it lets you set reasons why words have been added to the list, allowing you to quickly realise why a comment has been added to the moderation queue.

It is a pain when WordPress needs the ‘edit_posts’ role when you JUST need the Comments SubPanel. Which makes it hard if you want to assign somebody as a simple Comments Moderator.
This plugin will create a special user role called “Comments Moderator” that you can use to create any user account with. They will have access to the Comments SubPanel and all its functions, but nothing else 🙂

Create a custom role that enables only Comment Moderation actions and pages.
