From the Comments page on this blog’s dashboard:
Akismet has caught 30,138 spam for you since you first installed it.
You have no spam currently in the queue. Must be your lucky day. 🙂
This came after I’d bulk-deleted 265 comments, trackbacks and pingbacks which Akismet had identified as spam, pushing me over 30,000. I hit 20,000 back on June 25 last year, which means that since then the spam has been rolling in at over 45 comments a day.
