What I use:
function check_bad_content($string)
{
// Stuff that spammers post with:
$bad_strings = array('www.','/url]','ttp://','ttps://') ;
foreach( $bad_strings as $bad_string )
{
if ( ereg( $bad_string, $string ) ) return false ;
}
return true;
} // E-O- function check_bad_content
I permit _*NO*_ URL's on my message board. I guess you could just as
easily count them in the function above -- versus setting TRUE/FALSE.
