Help: What is a spam-block?

What is a spam-block?

Since we don't especially enjoy the Internet version of a particular type of canned meat, we have munged our published email addresses to prevent them from being harvested by "spambots". This is done in one of 2 ways: either by requiring you to press a button (most spambots are not that intelligent), or by appending a version of "no spam please" onto the email addresses given: please simply remove it when you mail us. Sorry for the inconvenience.

[Trivia: "Mung" is defined by The Jargon dictionary as "Mash Until No Good." It later became a recursive acronym, meaning "Mung Until No Good."].
