I've recently begun using this mod on my phpBB v. 2.0.22, and I'm already a very big fan. The only shortcoming I've found is in regards to how the "Number of offenses before user is automatically banned" setting works. I've tried setting this to a value of "1", and this seems to allow a single post "grace". If the user tries making a second post with an offending spam word, then they are banned. So, it takes two offending posts before a user is banned. I would prefer that as soon as a user attempts to make a post that contains a spam word, they are immediately banned (first offending post).
This seems to seems to have been briefly discussed a couple of places in this thread, notably here:
http://www.phpbb.com/community/viewtopi ... 5#p4300585
I made the change described there to "root\includes\spamwords.php" (changing > to >= in line 225), but it still does not seem to ban users after a single offensive post using a spam word.
