The link is to a report on Spam and the ways e-mail addresses are obtained by spammers. Their conclusion says that the most common way spammers get addresses is with address-harvesting programs which pick up any address shown on a website, and the best way to avoid them is to enter your address in a different format. e.g. "your.name at domain dot com" instead of "your.name@domain.com" This wouldn't stop someone who's aiming for your address, but it cuts down on random attacks.
