Has anyone noticed that the spammer seems to be on at certain times of day? It's enough to make a guess that they live in the eastern time zone of north america.

In fact it's rather strange -- surely the spam operation is automated and could operate 24/7 with a minimum of supervision? Yet the spammer disappears shortly after midnight eastern time, which suggests otherwise. Only one type of computer system is that incapable of remaining up for any length of time unassisted by a human. The spammer is running Microsoft Windows ME without any service packs.
