Munging refers to the deliberate alteration of an e-mail address online. This is done with the intent of making the address unusable for Web-based programs that build e-mail lists for spamming purposes. People who transmit unsolicited e-mail advertisements, called spam, often use programs called spambots to scour the Internet for e-mail addresses. Such addresses are easily recognized due to its unique format and the presence of the “@” symbol. Once munging is done, a person reading the document should easily tell that it is a munged e-mail address, and should be able to deduce the true e-mail address easily.
