Shill

A shill, also called a plant or a stooge, is a person who publicly helps or gives credibility to a person or organization without disclosing that they have a close relationship with said person or organization. Shills can carry out their operations in the areas of media, journalism, marketing, politics, sports, confidence games, cryptocurrency, or other business areas. A shill may also act to discredit opponents or critics of the person or organization in which they have a vested interest.

In most uses, ''shill'' refers to someone who purposely gives onlookers, participants or "marks" the impression of an enthusiastic customer independent of the seller, marketer or con artist, for whom they are secretly working. The person or group in league with the shill relies on crowd psychology to encourage other onlookers or audience members to do business with the seller or accept the ideas they are promoting. Shills may be employed by salespeople and professional marketing campaigns. ''Plant'' and ''stooge'' more commonly refer to a person who is secretly in league with another person or outside organization while pretending to be neutral or part of the organization in which they are planted, such as a magician's audience, a political party, or an intelligence organization (see double agent).

Shilling is illegal in many circumstances and under many jurisdictions because of the potential for fraud and damage. However, if a shill does not place uninformed parties at a risk of loss, the shill's actions may be legal. For example, a person planted in an audience to laugh and applaud when desired (see claque), or to participate in on-stage activities as a "random member of the audience", is a legal type of shill.

Etymology

The origin of the term "shill" is uncertain; it may be an abbreviation of "shillaber". The word originally denoted a carnival worker who pretended to be a member of the audience in an attempt to elicit interest in an attraction. Some sources trace the usage back to 1914, or as far back as 1911. American humorist Benjamin Penhallow Shillaber (1814–1890), who often wrote under the guise of his fictional character Mrs. Ruth Partington, the American version of Mrs. Malaprop, is a possible source.

Internet

In online discussion media, shills make posts expressing opinions that further interests of an organization in which they have a vested interest, such as a commercial vendor or special interest group, while posing as unrelated innocent parties. For example, an employee of a company that produces a specific product might praise the product anonymously in a discussion forum or group in order to generate interest in that product, service, or group. Web sites can also be set up for the same purpose. In addition, some shills use sock puppetry, where one person poses as multiple users.

In some jurisdictions and circumstances, this type of activity is illegal. The plastic surgery company Lifestyle Lift ordered their employees to post fake positive reviews on websites. As a result, they were sued, and ordered to pay $300,000 in damages by the New York Attorney General's office.

Reputable organizations may prohibit their employees and other interested parties (contractors, agents, etc.) from participating in public forums or discussion groups in which a conflict of interest might arise, or will at least insist that their employees and agents refrain from participating in any way that might create a conflict of interest.

Gambling

Both the illegal and legal gambling industries often use shills to make winning at games appear more likely than it actually is. For example, illegal three-card monte and shell-game peddlers are notorious employers of shills. These shills also often aid in cheating, disrupting the game if the ''mark'' is likely to win. In a legal casino, however, a shill is sometimes a gambler who plays using the casino's money in order to keep games (especially poker) going when there are not enough players. The title of one of Erle Stanley Gardner's mystery novels, ''Shills Can't Cash Chips'', is derived from this type of shill. This is different from "proposition players" who are paid a salary by the casino for the same purpose, but bet with their own money.

Marketing

In marketing, shills are often employed to assume the air of satisfied customers and give testimonials to the merits of a given product. This type of shilling is illegal in some jurisdictions, but almost impossible to detect. It may be considered a form of unjust enrichment or unfair competition
