Developer-tuned spam

I think I've got a pretty nice junk mail filter in my Outlook, but sometimes one odd spam e-mail comes through. Today's lonely spam was titled "The implementation of the IPersistStream standard interface deserves a more detailed examination". Wow, that's clever. Sounds like we developers are one of the last islands of people that don't have spam tailored to us. Or, using a rather sensible subject line just makes it easier to fool the mail filters. Just like combining both German and English in the same message. Somebody must run a full-time job figuring out these.
