 As everyone knows how regular expression work funktion wp_blacklist_check
 will block any comment with the word 'specialist' if blacklist contains
 word 'cialis'.

 This can be easily fixed by adding word boundaries around word from
 blacklist while constructing the pattern.

 Here is the solution:

 instead of line 666 (WP202) in wp-inclides/functions-post.php
 $pattern = "#$word#i";
 use this:
 $pattern = "#\b$word\b#i";

 This will let comment with word 'specialist' through and stop comment with
 word 'cialis'.
