"There will be an enormous drop in HTML spam, and we will have more text-based and chatty spam," said Graham-Cumming. But "the volume of spam will increase as spammers send variants of messages to get them through."Link
Although no spammer has yet to fool every Bayesian filter, some tricks work better than others. One recent spam employed a trick that misspelled almost every word in the body, but was still coherent enough to get the gist through.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
