Twitterbot

A Twitterbot is a program used to produce automated posts on the Twitter microblogging service, or to automatically follow Twitter users. Twitterbots come in various forms. For example, many serve as spam, enticing clicks on promotional links. Others post @replies or automatically "retweet" in response to tweets that include a certain word or phrase. These automatic tweets are often seen as fun or silly. Some Twitter users even program Twitterbots to assist themselves with scheduling or reminders.
