The mod is working nicely on our forum. Yesterday it moderated a spam that got through registration and filtering.
Here's a bit of feedback from the user whose report caused the spam to be moderated. If you ever work on another version, might be worth considering a tweak to the report page to tell the user their report cause moderation and avoid returning them to the thread, if it's no longer visible.
Thanks again for writing this. It's really nice to get the occasional spam which evades all other anti-spam measures out of everyone's sight.
