Ahh! Under attack!
I woke up this morning to find 95 new emails in my inbox. Three of them were random (not spam) emails but the other 92 were blog-related emails. 90 of them were requests for moderation of comments in my 3 and a half month old Flickr post. The other two were comments that slipped through Wordpress' filters and were posted as comments.
The emails were dated (timed?) 7:41am through 8:09am, so all this took place within a half hour. Since it took me less than 5 minutes to clean up and only two comments actually showed up on the site, it just goes to show how futile these spam attacks really are.
