Maria and I were discussing the increasingly esoteric and convoluted nature of spam, just now, including the fact that much of bulk email no longer serves a discernible purpose. I frequently receive spam from nonsense names, advertising nothing, free of hyperlinks or parsible sentences.

I pointed out that one reason it’s gotten so complicated is the constant, high-speed arms race between spammer and anti-spam software vendor; as new regular expressions are devised and new efforts made to beat them, whole fields of technique can be created and discarded in a week. And then Maria said something that chilled me to my very bones.

“What if,” she said, “the vendors are putting spam out there just to keep selling their software?”

I’m terrified, now, that she might be right.

Anyway, read Spam As Folk Art.
