Specialized search engines known as spambots search the web for addresses that can be added to spam lists. Some legitimate websites also sell lists of their customers to purveyors of spam email. Spammers often share their email lists with other spammers.

Spammers often thwart simple filters with intentional misspellings of words commonly used in spam. Advanced filters use word frequency and patterns to try to identify spam.
