The campaign is centered on produce labels that show how many miles a bag of clementines traveled, for example. The labels include bar codes and, when scanned, the food miles for each item appears by its price on the receipt and a total appears on the bottom. This little puppy is one of three Science Diet used to demonstrate the power of its dog food. Pet food company Science Diet contracted with JWT Advertising to run a series of print ads that showed a veterinarian examining three different dogs.

Ferrara says. There are creative bots such as MoMa Robot, which tweets random images from the collection of the Museum of Modern Art, and Dear Assistant, which answers questions in the style of Siri and Cortana. Humor bot We Didn't Start It grabs info from Google Trends. Uses it to write new lyrics for a Billy Joel song. And many bots just provide useful information automatically. SF QuakeBot, for example, tweets U.S. Geological Survey seismic data for the San Francisco area. David Carroll, an associate professor of media design at the New School in New York. But bots can also be used to commit fraud and identity theft and to carry out misinformation campaigns. According to Carroll, an intermediate-level web programmer is capable of building a "botnet," in which a legion of bots can be controlled and coordinated. For those who want to outsource the job, Carroll says that pre-built botnets are available on the dark web. What's the solution to the bot problem? Detection programs such as Indiana University's Botometer can scrutinize a Twitter account's activity in an effort to determine whether it's an actual person or a bot. Gregory Maus, an Indiana University graduate student who has studied bots extensively, said in an email that Twitter's countermeasures have proven surprisingly effective so far, wiping out 90 percent of the 450,000 mercenary bots that his research group was tracking. Wiping out malicious bots wouldn't necessarily solve social media's disinformation dilemma, Ferrara notes. Some efforts, like the Russian conspiracy to interfere in the 2016 U.S.
