Oi! So my theory proves out. Facebook is a vector for spam. In their defense, it's a bit my fault for linking here from there. Here a spider can find my actual email and email me offers top increase my man hood.
Here's the way of it. The spider hits my very public facebook page (while it's active). It follows my links, in this case just one to here. It spiders here looking for mailto s. It farms those out to spam zombies.
I turned my facebook page off again 3 days ago. At the height of the deluge, I was getting about 3 or 4 emails an hour. After 3 days, enough of those zombies have gone down or changed targets that I'm down to about 1 every three hours. By this time next week I should be back down to 1 or 2 a day.
And those 2 people need to frickin' install some AV software.
