Spotting spam is hard for humans

A blog entry from the creator of SpamOrHam? (a site that asks users to teach a computer what is and isn't spam by voting on messages) reveals humans' extreme difficulty in distinguishing spam from not-spam. Some of the messages that his users have mistaken for legitimate are the crudest phishing scams, while some of the messages that people often rated as spam are legit, including jokes and discussion-threads from a sales-team.
