I want to find a plugin about spam filter.
first i want to build the word library in my local site.
and can cut words.
such as while has (fuc.k you) in the word library.and the user submit (fuc.k ** you).so certainly it won't match.
and efficient.

(the dot between fuc.k is to stop the codecall from filter this word,and of course it's an example how to ingore the filter)

OR
if you don't know any plugin , you can also write your thought about how program.

i hope you guys know what i mean.god bless.

Plugin to what system?

I would recommend you try something like this. It's how I've done it in the past:

<?php


// A list of all the words you want to ban

$filterlist = array('silly', 'stupid', 'wicked');


// The message you want to filter

$message = 'That silly girl went on a date with that stupid stoopid boy who was wicked.';


// Run the filter function

echo (filtermessage($filterlist,$message));


/* -------------------------------------------------------------------------------

	Function: filtermessage

    Description: Filter out a selection of words from a message and replace

				them with a word of your choice

    Usage:	filtermessage( array('silly'), 'silly person', 'removed');

   ------------------------------------------------------------------------------- */

function filtermessage($filterlist, $message, $replace = '[removed]'){


	foreach($filterlist as $currentword){

		// Remove any words straight out from the list

		$message = eregi_replace(trim($currentword), ' ' . $replace . ' ',$message);


		// Get each individual word

		$words = explode(' ', $message);


		// Check each word for a phonetic match

		foreach($words as $word) {

			if(metaphone(trim($word)) == metaphone(trim($currentword))) {

				$message = eregi_replace($word, ' ' . $replace . ' ',$message);

			}	

		}

	}

	return $message;


}


?>
