High Quality Content by WIKIPEDIA articles! E-mail spambots harvest e-mail addresses from the Internet in order to build mailing lists for sending unsolicited e-mail, also known as spam. Such spambots are web crawlers that can gather e-mail addresses from Web sites, newsgroups, special-interest group (SIG) postings, and chat-room conversations. Because e-mail addresses have a distinctive format, spambots are easy to write. A number of programs and approaches have been devised to foil spambots. One such technique is known as address munging, in which an e-mail address is deliberately modified so that a human reader (and/or human-controlled Web browser) can decode it but spambots cannot. This has led to the evolution of more sophisticated spambots that are able to recover e-mail addresses from character strings that appear to be munged, or instead can render the text into a web browser and then scrape it for e-mail addresses. Alternative transparent techniques include displaying all or part of the e-mail address on a webpage as an image, a text logo shrunken to normal size using inline CSS, or as text with the order of characters jumbled and restoring the order using CSS, where users are then able to see the address.
