This plugin has been developed by BlackMelvyn from this <a href="http://www.theblackmelvyn.com/" title="SEO Black Hat blog" rel="nofollow ugc">blog SEO Black Hat</a> thanks to a script coded by Tiger from <a href="http://www.seoblackout.com/" title="Référencement Google" rel="nofollow ugc">Blog SEO BlackOut: Techniques référencement Google</a>. 
It compares the language contained in the comment text to the languages that you allow in your admin panel for this blog. 
There is a minimum confidence index that should be reached for the comment to be considered as valid. 
Then, if the comment is sorted a valid, it is held for moderation. 
On the other hand, the plugin counts the number of links contained in the comment, and if there is a suspicion of comment spam, it blocks the comment and adds it to trash. 
Finally, you get rid of all these automated spam bots that try and spoil your blog with their nasty unuseful comments, you save database space and you save time as you do not have to sort out what is spam and what is not! 
We recommend that you use this plugin in conjunction with the keywords filter built in WordPress for more efficiency.

This plugin prevents comments spamming using language verification.

Adds a hidden field to comment forms, which will subsequently be auto-filled by spam-submitting robots. If the form 
submission contains a value, the comment will not be saved, because only robots will see the field and fill it out.
Simple!
Any form which is processed using the hook <code>comment_form_after_fields</code> (building the form HTML) and <code>preprocess_comment</code> 
(for processing the form submission) will be extended with this functionality.
This plugin doesn’t block or catch any form submissions which have been filled manually in a browser, so you may still 
receive the occasional advertising or sales message as a post or page comment. However, blocking automatically-generated 
spam messages will reduce the number of unwanted messages greatly.
