can modify the sql to fetch the reason...
like "SELECT * FROM wcddl_blacklist"

sample code:
PHP Code: 
$list mysql_query("SELECT * FROM wcddl_blacklist");
$out .= "---------------------\nBlacklisted URLs\n---------------------\n";
   while(
$l mysql_fetch_assoc($list))
   
$out .= $l[url]."\n".$l[reason]."\n"
and printing it..


not tested.. the code.. but seems it will be like this...
