Since my Mac got irredeemably cranky a month ago I've been unable to alter the junk mail status of messages (when I try, Mail.app crashes. When I restart Mail, the status is unchanged...) and it had begun registering a lot of false positives, so I had to switch spam filtering off.
As a result I've been accumulating spam very quickly indeed, thank you. This evening the count stood at my year of birth (1977), and is now telling me when I left school (1993). I wonder if it will get A Levels or my degree right?
Update No, it went straight to pensionable age.
