Email addresses

An email address like fred@somewhere.com is easier to decode. Before the "@" symbol is the username of the email box owner. After the "@" is the domain that hosts the email box. Spammers use software 'robots' to search webpages and newsgroups for email addresses to use in their mass-mailings: the robots look for text containing an "@" and at least one dot.

To counter this, many people "munge" or alter their email address to camouflage them. For example, fred AT somewhere.com or fred@somewhereNOSPAM.com. Humans can see the obvious munging and fix the address, but 'spambots' either don't recognise it as an email address or the spammers could not be bothered manually fixing munged addresses.
