This happened because I used to have a spam archive, collecting every spam email I had received since c.1997. I don’t exactly know how the interview came about — I was just contacted on the morning of the interview by a researcher from Radio 4. But being a big fan of the BBC of course I was happy to come in to London and talk to them.
I expected to be in a studio discussion, perhaps with others, but that wasn’t quite how it happened. About an hour after I arrived, I was shuffled into a small booth and connected up to Eddie who was “on the line” in some other London studio. Nevertheless we had a conversation about spam and other things. What was finally broadcast was heavily edited and condensed down to about 4 minutes, from an original which must have been 10 minutes or more.
I still to this day collect every email — spam or otherwise — that I receive, but I no longer put them online because that caused all sorts of problems. My total mail archive is 11 gigabytes, of which 7.5 gigabytes is classified as spam [note this is just a "du" of various compressed files]. The earliest spam is from Oct 2 1997 (an advert for “Teeth Bleaching and Whitening”), and the latest is almost certainly from about 1 minute ago, whenever you are reading this posting.
