This has led to the evolution of more sophisticated spambots that are able to recover email addresses from character strings that appear to be munged, or instead can render the text into a web browser and then scrape it for email addresses. One such technique is address munging, in which an email address is deliberately modified so that a human reader (and/or human-controlled web browser) can interpret it but spambots cannot. Because email addresses have a distinctive format, such spambots are easy to code.Ī number of programs and approaches have been devised to foil spambots. Such spambots are web crawlers that can gather email addresses from websites, newsgroups, special-interest group (SIG) postings, and chat-room conversations. Email spambots harvest email addresses from material found on the Internet in order to build mailing lists for sending unsolicited email, also known as spam.
