Appreciate the work put into this--while I know it's something you built for your own site, I was wondering if you've tested recently with the latest version of IPS4. Particularly interested in the keyword blocker. Ran a few test posts with a few expressions (including your language blocks) and the offending post generates an EX2 error code. Funny thing is, the post still makes it through unmoderated, but does not trigger a notification email.
