Forum spambots surf the web, looking for guestbooks, wikis, blogs, forums and other types of web forms which it can then use to submit bogus content. These often use OCR technology to bypass CAPTCHAs. Some spam messages are targeted towards readers and can involve techniques of target marketing or even phishing, making it hard to tell real posts from the bot generated ones. Other spam messages are not meant to be read by humans, but are instead posted to increase the number of hyperlinks to a particular web site, to boost its search engine ranking.
This category of spambot 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.
One way to prevent spambots from creating automated posts is to require the poster to confirm their intention to post via e-mail. Since most spambot scripts use a fake e-mail address when posting, any email confirmation request is unlikely to be successfully routed to them. Some spambots will pass this step by providing a valid email address and use it for validation, mostly via webmail services. Using methods such as security questions are also proven to be effective in curbing posts generated by spambots, as they are usually unable to answer it upon registering.
The term spambot sometimes has an inverse meaning, referring to a program designed to prevent spam from reaching the subscribers of an Internet service provider (ISP). Such programs are more often called e-mail blockers or filters.
Blocking software may inadvertently prevent a legitimate e-mail message from reaching a subscriber. This can be prevented by allowing each subscriber to generate a whitelist, a list of specific e-mail addresses the blocker should let pass.
