Without any intervention from me (that I recall), Spam Karma has figured out how to send digests (1 email per 10 spam comments) rather than 2 emails per comment. It’s working beautifully now.
I still have the same low-level migraine (what, 2 weeks now?). Maybe it’s the new glasses.
Hmm … now I will have to send you 10x as much spam. Curses! Foiled again.
