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 simple spambots cannot. This has led to the evolution of sophisticated spambots that can recover e-mail addresses from character strings that appear to be munged, or rendering the text into a web browser and then scraping the rendered text for email 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. Although these methods combat spambots, some are not compatible with web page accessibility standards.
This category of spambots has gained considerable notoriety since November 2006, with the introduction of XRumer, a forum and wiki spambot which can often bypass many of the safeguards administrators use to reduce the amount of spam posted.
The easiest way to prevent spambots from posting on forums, wiki, guestbook, etc. is to enable email activation by installing a mail server on the host (eg: Sendmail, Postfix, Exim.), since most spambot scripts use fake or randomly generated names on real email providers, the emails will mostly never be successfully routed to them.
