Sociology of con games

a member of a con operator's team who poses as an ordinary participant so the target trusts the game.

In the study of confidence games a shill is a member of the operator's team who poses as an ordinary, independent participant, appearing to win or to play in earnest so that the real target trusts the game and commits. The construct is a planted confederate who manufactures a false impression of genuine, disinterested activity. Goffman's 1952 On cooling the mark out describes the shill's role within the division of labour of a con. The same construct recurs wherever staged participation is used to influence onlookers, including auctions and online reviews.[1]

Unit
A planted participant simulating independent, genuine engagement
Recovery means
Not applicable
Measured by
Identified by the shill's covert tie to the operator and the absence of genuine stake in the outcome

Auction markets

a bidder secretly acting for the seller who bids without intent to buy, solely to drive the price up.

In auctions a shill is a bidder secretly acting for the seller who places bids with no intention of buying, solely to drive the price up or to lift it past the reserve. It is the same planted-confederate construct as in a con game, specialised to bidding: the shill simulates genuine competitive demand that does not exist. Wang, Hidvegi, and Whinston's 2002 Shill bidding in multi-round online auctions modelled how such bidding distorts outcomes in online markets. The underlying mechanism, fabricated participation to mislead a target, is identical to the sociological and review cases.[2]

Unit
Seller-aligned bids made only to raise the price, not to win
Recovery means
Not applicable
Measured by
Detected through bidding patterns, repeated non-winning bids, and accounts linked to the seller

Online review systems

a paid or planted review posing as an ordinary customer's honest opinion to promote or disparage a product.

In online marketplaces a shill review is a paid or planted review written to pose as an ordinary customer's honest opinion in order to promote or disparage a product, a practice also studied under opinion spam. It is the same construct as the con-game shill and the auction shill, now realised in text: a confederate feigning disinterested endorsement. Jindal and Liu's 2008 Opinion spam and analysis framed the detection of such deceptive reviews as a data-mining problem. The recurring referent across all three systems is manufactured independent participation deployed to mislead an audience.[3]

Unit
Reviews posing as independent that covertly serve the promoter
Recovery means
Not applicable
Measured by
Flagged by duplicate or templated text, reviewer behaviour anomalies, and rating distortions
