I can't believe the extent that spammers go through to get their "junk mail" in front of people. I can only assume that there is some percentage of the population that actually responds to the spam - otherwise the senders would give up on it (right?).
At ORCS Web we have spam filtering devices in front of the mail servers, and they do a pretty good job. Now I'm personally dealing with blog spam though. Several times a day I get comments to my blog posts - mainly the "Data Transfers: Why GB/month" post for some reason. I usually notice the spam within a few minutes and delete it (no, I don't sit and stare at my blogs all day - I get an email notification on all comments).
It's a waste of time. A waste of system resources. A waste of money. Go away spammers (please).
