Zebras Get Less Spam Than Aardvarks

MojoKid writes "A recent study (PDF) by Richard Clayton at Cambridge University determined that the first letter of a someone's email address directly affects how much spam they receive. As shown in the graph at either link above, email addresses with numbers as their first characters receive even fewer spam emails. The corpus used in the study was 8 weeks' worth of email from the UK ISP Demon Internet, just over half a billion messages, of which 56% was deemed to be spam."

    Spammers will now alter their programs to start with "z" and numbers, so they can get the people who aren't as desensitized by spam.

    Indeed. The conclusion that I'd draw from presented data is that there are more e-mail addresses beginning with 'a' than with 'z' (and that very few addresses begin with a number). Even the percentage of spam is nearly meaningless. To find anything about which addresses receive more spam, you should look at the average amount of spam per e-mail address in a given group, not the total number of messages.
