Time Line

March 2016
Our web site contact email address is compromised, forcing us to change it near the end of the month.

Our ISP implements more stringent spam filtering.
December 2006
All mail sent to the "abuse" address in our domain is deleted unread at the ISP level from mid-month.
March 2006
A disc crash and change of email reader results in the loss of most of email at one of our academic addresses. No further spam from this account is reported.

Since spammers have stolen and rendered unusable our private email addresses, we are forced to get new addresses; hence the huge drop in spam numbers.
