Internet botinternet bot, internet bots definition
An Internet bot, also known as web robot, WWW robot or simply bot, is a software application that runs automated tasks scripts over the Internet Typically, bots perform tasks that are both simple and structurally repetitive, at a much higher rate than would be possible for a human alone The largest use of bots is in web spidering web crawler, in which an automated script fetches, analyzes and files information from web servers at many times the speed of a human
Given the exceptional speed with which bots can perform their relatively simple routines, bots may also be implemented where a response speed faster than that of humans is required Common examples including gaming bots, whereby a player achieves a significant advantage by implementing some repetitive routine with the use of a bot rather than manually, or auction-site robots, where last-minute bid-placing speed may determine who places the winning bid – using a bot to place counterbids affords a significant advantage over bids placed manually
Bots are routinely used on the internet where the emulation of human activity is required, for example chat bots A simple question and answer exchange online may appear to be with another person, when in fact it is simply with a bot
While bots are often used to simply automate a repetitive online interaction, their ability to mimic actual human conversation and avoid detection has resulted in the use of bots as tools of covert manipulation On the internet today bots are used to artificially alter, disrupt or even silence legitimate online conversations Bots are sometimes implemented, for example, to overwhelm the discussion of some topic which the bot's creator wishes to silence The bot may achieve this by drowning out a legitimate conversation with repetitive bot-placed posts which may in some cases appear to be reasonable and relevant, in others simply unrelated or nonsense chatter, or alternatively by overwhelming the target website's server with constant, repetitive, pointless bot-placed posts These bots play an important role in modifying, confusing and silencing conversations about, and the dissemination of, real information regarding sensitive events around the world
The success of bots may be largely due to the very real difficulty in identifying the difference between an online interaction with a bot versus a live human Given that bots are relatively simple to create and implement, they are a very powerful tool with the potential to influence every segment of the World Wide Web
Efforts by servers hosting websites to counteract bots vary Servers may choose to outline rules on the behaviour of internet bots by implementing a robotstxt file: this file is simply text stating the rules governing a bot's behaviour on that server Any bot interacting with or 'spidering' any server that does not follow these rules should, in theory, be denied access to, or removed from, the affected website If the only rule implementation by a server is a posted text file with no associated program/software/app, then adhering to those rules is entirely voluntary – in reality there is no way to enforce those rules, or even to ensure that a bot's creator or implementer acknowledges, or even reads, the robotstxt file contents

IM and IRC
Some bots communicate with other users of Internet-based services, via instant messaging IM, Internet Relay Chat IRC, or another web interface such as Facebook Bots and Twitterbots These chatterbots may allow people to ask questions in plain English and then formulate a proper response These bots can often handle many tasks, including reporting weather, zip-code information, sports scores, converting currency or other units, etc Others are used for entertainment, such as SmarterChild on AOL Instant Messenger and MSN Messenger
An additional role of IRC bots may be to lurk in the background of a conversation channel, commenting on certain phrases uttered by the participants based on pattern matching This is sometimes used as a help service for new users, or for censorship of profanity
There has been a great deal of controversy about the use of bots in an automated trading function Auction website eBay has been to court in an attempt to suppress a third-party company from using bots to traverse their site looking for bargains; this approach backfired on eBay and attracted the attention of further bots The United Kingdom-based bet exchange Betfair saw such a large amount of traffic coming from bots they launched a WebService API aimed at bot programmers through which Betfair can actively manage bot interactions

Another, more malicious use of bots is the coordination and operation of an automated attack on networked computers, such as a denial-of-service attack by a botnet Internet bots can also be used to commit click fraud and more recently have seen usage around MMORPG games as computer game bots A spambot is an internet bot that attempts to spam large amounts of content on the Internet, usually adding advertising links

- Bots may be used on internet forums to automatically post inflammatory or nonsensical posts to disrupt the forum and anger users
The most widely used anti-bot technique is the use of CAPTCHA, which is a form of Turing test used to distinguish between a human user and a less-sophisticated AI-powered bot, by the use of graphically encoded human-readable text Examples of providers include Recaptcha, and commercial companies such as Minteye, Solve Media, and NuCaptcha Captchas, however, are not foolproof in preventing bots as they can often be circumvented by computer character recognition, security holes, and even by outsourcing captcha solving to cheap laborers
