So where is the spam coming from? An earlier report from MessageLabs lists Florida and Texas.
Mark Sunner, CTO of MessageLabs, said: "Florida and Texas are the only two US states where bankruptcy laws treat the company or the individual so favourably."
"The laws in Florida actually favour the spammer," added Sunner. He told silicon.com that spammers base themselves there because in their worst case scenario - getting caught and being put out of business by hefty penalties - they will be able to keep possession of assets "bought with their ill-gotten gains" such as cars and houses.
Boca Raton, Florida has the dubious distinction of being the spam capital of the world.
