Spammers Getting Dumber?

Though I’ve always gotten a lot of spam, it seems like lately much of it is just bad. Not in a moral sense, though much of it is of course that, but in a technical sense. I’ll get a message with a subject promising me that I can make $100,000 a month working from home, but when I open it, there’s nothing there. (Oh, the suspense.) Or one of the 5-10 messages a day I get with Viagra in the subject line has a MIME message that’s mangled to the point where all I get is gibberish when I open it. My latest favorite was an herbal breast-growth formula which, while it was actually legible, missed its target market pretty widely.
