When munging is done, it should be in such a way that a person reading the document (as opposed to a program scanning it) can easily tell that it is a munged e-mail address, and can easily and unmistakably deduce the true e-mail address. Here are four examples of the munging of stangib@reno.com:

stangib at reno dot com
s-t-a-n-g-i-b-at-r-e-n-o-d-o-t-c-o-m
stangibNOSPAM@reno.com
My username is stangib, and the domain name is reno dot com.

Munged e-mail addresses can be useful in Web sites, e-mail correspondence, chat rooms, and postings to newsgroups and special interest groups (SIGs). However, some experts advise against the practice because it may violate the Terms of Service (TOS) of the subscriber's Internet service provider (ISP). Munging should not be used if a response to a particular correspondence is desired. For example, when making an online purchase, the seller typically asks for an e-mail address in order to send a confirmation. If the address is munged, the confirmation will not reach the purchaser.

It is important that munged e-mail addresses not be mistaken for legitimate addresses belonging to third parties. If an innocent person, corporation, or institution is harmed as a result of a munged e-mail address, civil or criminal action could result. Fake usernames or domain names are particularly dangerous in this respect.

The term munging probably derives from the acronym mung (pronounced just as it looks), which stands for "mash until no good." It may also derive from the hackers' slang term munge (pronounced MUHNJ), which means "to alter information so it is no longer accurate."
