New technologies has made it easier to catch people doing unethical things. Two recent cases in point:

• Possible crossword puzzle plagiarism. Yes, really. As FiveThirtyEight reports:

A group of eagle-eyed puzzlers, using digital tools, has uncovered a pattern of copying in the professional crossword-puzzle world that has led to accusations of plagiarism and false identity.

Since 1999, Timothy Parker, editor of one of the nation’s most widely syndicated crosswords, has edited more than 60 individual puzzles that copy elements from New York Times puzzles, often with pseudonyms for bylines, a new database has helped reveal. The puzzles in question repeated themes, answers, grids and clues from Times puzzles published years earlier. Hundreds more of the puzzles edited by Parker are nearly verbatim copies of previous puzzles that Parker also edited. Most of those have been republished under fake author names.

• Bridge. Cheating in bridge isn’t exactly a new development. As the New Yorker reports, setting up a website to figure out exactly how people are cheating is:

When [Boye] Brogeland made his first announcement, his evidence against [Lotan] Fisher and [Ron] Schwartz consisted solely of what he believed to be a collection of suspicious hands; he still didn’t know how they might be exchanging information. A few days later, he created a new Web site, called Bridgecheaters.com, and posted three YouTube videos from the 2014 European Team Championships, which Fisher and Schwartz’s team had won. Each video had been shot from a camera mounted near the table. It showed all four players, as well as the table paraphernalia of modern tournament bridge: four bidding boxes (containing each player’s pre-printed bidding cards); a felt-covered bidding tray (on which the players place bidding cards before sliding it back under the screen); and a plastic duplicate board (a flat, rectangular box in which four pre-dealt hands have been delivered to the table). Brogeland asked for help from other players, and the search for evidence immediately became a collaborative international project.
