I have been running Spam Karma 2 Alpha on this site for the past few days and it seems much better at catching spam than the original Spam Karma including catching all the trackback spam that had been slipping through.
I was however missing the digest emails that Spam Karma generated so I wrote a little plug-in for Spam Karma 2 this evening “sk2_pjw_daily_digest_plugin“. This sends a digest email every n hours with a report on the recently caught spam (since last mail basically) much the same as you can see through the Spam Karma 2 plug-in options page.

The plug-in can be downloaded here – A new static page for the plugin can be found here (requires Spam Karma 2 – Alpha 2) – If it eats your wordpress install it’s you fault not mine!

Example Digest Report:

There are currently 0 comments in moderation
There have been 2 in the last 1 hours.
