Filter Comments brings a powerful new way to protect your posts from bad comments. Negative comments on your blog posts has been a nightware for every blogger, but now you can easily remove bad words from your post comments.
Filter Comments perform following functions: 
* Specify words that needs to be replaced/removed 
* Specify a replacer e.g. replace “ugly” to “nice” 
* View actual comment from the dashboard 
* Add as many words as you like
If you want to remove the word altogether, you can just leave the “Replace with” field and that work will no longer appear in your post comments.
<h3>Credits</h3>
The idea for Filter Comments came from a desire that you do not have to review each and every comment before approve. You can approve all comments but filter some words from it. 
Thanks.
