A Site

With a focus on the online phenomena of scamming and scambaiting, this article explores users’ communicative activities on Reddit’s r/scambait subreddit. Drawing on a representative corpus viewed through grounded theory, we establish the basic categories of posts and then unpack those further to reveal the deceptive practices being undertaken by both scammers and scambaiters, as well as Redditors’ untruthfulness in their fabricated posts. The analysis reveals that the r/scambait subreddit exists as a site of humorous entertainment arising from various forms of deception. Scammers’ deceptive strategies are depicted as amusingly naïve and inefficient, while scambaiters’ deceptive messages targeted at scammers demonstrate great creativity and wittiness. In both cases, scammer-victims are disparaged for being immensely gullible or downright stupid; and Redditors earn online plaudits for submitting the most upvoted posts. Our significant finding is that posts such as those at r/scambait should never be taken at face value due to their inherent epistemological ambiguity, to which the users choose to remain oblivious or indifferent. Furthermore, on a general plane, this study indicates a potential shift in the emic understanding of the concept of “scambaiting” from a punitive measure and an educational instrument to a creative practice geared toward posters’ kudos and users’ joint humorous experience through “baitertainment” and “scamusement.”

Limiting Case

In comparison with the general plane quartic on the one hand, and the curves having either two or three nodes on the other, the uninodal curve has been neglected. Many of its properties may of course be deduced from those of the general quartic in the limiting case when an oval shrinks to a point or when two branches approach and ultimately unite. The modifications of properties of the bitangents are shewn more clearly by Geiser's method, in which these lines are obtained by projecting the lines of a cubic surface from a point on the surface. As the point moves up to and crosses a line on the surface, the quartic acquires a node and certain pairs of bitangents obviously coincide, viz. those obtained by projecting two lines coplanar with that on which the point lies. A nodal quartic curve and its double tangents may also be obtained by projecting a cubic surface which has a conical point from an arbitrary point on the surface. Each of these three methods leads us to the conclusion that, when a quartic acquires a node, twelve of the double tangents coincide two and two and become six tangents from the node, and the other sixteen remain as genuine bitangents: the twelve which coincide are six pairs of a Steiner complex.

Methodological Debate

Despite the fact that the study of politics has become increasingly empirical, quantitative and “behavioral” in recent years, and despite the apparently increasing tendency to feel that whatever meaningful debate ever existed between the behavioralists and the anti-behavioralists has ended, should end, or at least has become irrelevant since a more sophisticated and empirically productive behavioralism now predominates in virtually all fields of the discipline, the methodological debate continues, diminished perhaps in quantity but not in intensity.This essay is based on the assumption that the antagonists concerned with the methodological issues raised by the “new science of politics” have but rarely focused precisely on the arguments raised by their opponents. A second motivating assumption is that nothing constructive, conciliatory or conducive to the integration of the discipline can be done “until the issues have been squarely confronted on the basic and general plane of philosophy….” A thorough analysis of all of the meaningful issues involved can only be a task of long-range proportions. But in the hope of bringing about some degree of communication, if not reconciliation, it is my intention in this essay to bring one of these issues into sharper focus, to show that almost despite themselves, some of the critics and proponents of the “new science of politics” have addressed themselves to the problem of concept formation, and that despite their proclaimed differences are talking at cross-purposes about a similar problem. Indeed, it will be seen that the conflict between the “traditionalists” and the “behavioralists” is utterly dependent—in the area of concept formation—upon an outmoded positivistic interpretation of behavioral science and a misguided reaction on the part of some political theorists to that obsolete conception.
