P.S.  Here (repeated) are the things about which we were after 
explanation if possible:

"I also am interested in an explanation of aspects of the statistics.

I *think* the drop in the second half of September, and sustained lower 
levels of submitted spam since then, correspond to the change in the 
limit on the age of accepted spam from 3 to 2 days, which IIRC also went 
with a recommendation that only spam less than 24 hours old was of any 
real usefulness to Spamcop.

Can someone confirm this?

The spikes in late-Oct and January are intriguing.  Being a Mac-only 
user now, I'm not familiar with recent Windows virus/worm outbreaks, 
which perhaps provide an explanation?  If so, which ones correspond to 
the spikes?

Also, can anyone explain why the spike in submitted spam in late-Oct 
went with a corresponding spike in reports sent, while the spikes in 
submitted spam in January did not?

Cheers."
