Different types of email harvesters are available, including open-source email harvesters and proprietary pieces of software. They may be transferred or sold on certain “black hat” internet sites. Some were built for specific websites such as Craigslist or Facebook. Those who are looking to collect bulk email addresses can also use things like a directory harvest attack to mine email addresses, or simply buy lists from other parties.
