I am unable to reproduce it so I can only guess.
It has been brought up enough times that I am assuming if one of the Staff had “rejected” and didn’t follow through with the work flow (unSilence, Suspend, leave a Staff Note) someone would have admitted their involvement with the account.
I have seen “post rejected” for “typed too fast” posts in the Staff Actions logs.
My first guess was that the posts were messages that I couldn’t access, but that does not seem to be the case.
My current guess is that there is some kind of asynch happening and some posts get caught both by “typed too fast” and by Akismet. eg.
- a post gets put in queue for “typed too fast”
- Akismet catches post, deletes it (typically it would be put in queue or wait for “too fast” to be approved)
- because Akismet deleted the “raw” post, it’s like the post never happened
- because it “never happened”, nothing is logged
