Lately I've been receiving 2-3 non-advertisement spams a day. It's the rare type of spam that isn't caught by thunderbird's bayesian filter. All they are is a few random phrases designed to bypass spam blockers. I view the source to confirm. There's no sort of advertisement. No URL's. No meaningful information in the headers. No html. No images. It's 100% random plaintext. And these are tiny spams, unlikely to choke many email servers with their volume. All they're doing is sending out possibly hundreds of millions of spams a day with nothing but random text, having no commercial value whatsoever, marketing or otherwise. That's the dumbest marketing plan I've ever seen. What's the point of sending spam if not to make money?
