Autoposters

I found this picture in my spam mailbox. I am guessing it means I've spent too much time on the computer when the word "autoposters" in a subject line makes me think it's about some kind of software, and not pictures of cars.

Why would a Brazilian poster company send spam to me, and in Spanish?

I can see how people can sell things with clever advertising. My first thought was "ooh, that looks nice, maybe I should get one". But that's idiotic, I'm really not that interested, and I don't have the wall space.
