I have switched Spam Karma off... temporarily, to test
Typepad's new Antispam plugin
As is well known I am not a huge fan of collective intelligence as the sole arbiter of whether a comment is "spam or ham", and long term I am most likely to switch back to Spam Karma, possibly using Typepad Antispam as an additional filter.
I am also going to grab the code from Igor so I can test Typepad Antispam in conjunction with his
Project Honeypot though I think that too is best served as a Spam Karma filter/plugin with probably a high threshold.
Typepad Antispam was quite easy to set up
