While turning yourself into a human captcha may be a fairly effective approach to operational security, even the most paranoid admit these checks create an atmosphere of distrust before two parties have even had the chance to really connect. They can also be a huge time suck. “I feel like something’s gotta give,” Yelland says. “I’m wasting so much time at work just trying to figure out if people are real.”
Jessica Eise, an assistant professor studying climate change and social behavior at Indiana University Bloomington, says her research team has been forced to essentially become digital forensics experts due to the amount of fraudsters who respond to ads for paid virtual surveys. (Scammers aren’t as interested in the unpaid surveys, unsurprisingly.) For one of her research projects, which is federally funded, all of the online participants have to be over the age of 18 and living in the US.
“My team would check time stamps for when participants answered emails, and if the timing was suspicious, we could guess they might be in a different time zone,” Eise says. “Then we’d look for other clues we came to recognize, like certain formats of email address or incoherent demographic data.”
Eise says the amount of time her team spent screening people was “exorbitant” and that they’ve now shrunk the size of the cohort for each study and have turned to “snowball sampling,” or recruiting people they know personally to join their studies. The researchers are also handing out more physical flyers to solicit participants in person. “We care a lot about making sure that our data has integrity, that we’re studying who we say we’re trying to study,” she says. “I don’t think there’s an easy solution to this.”
Barring any widespread technical solution, a little common sense can go a long way in spotting bad actors. Yelland shared with me the slide deck that she received as part of the fake job pitch. At first glance, it seemed legit, but when she looked at it again, a few details stood out. The job promised to pay substantially more than the average salary for a similar role in her location and offered unlimited vacation time, generous paid parental leave, and fully covered health care benefits. In today’s job environment, that might have been the biggest tipoff of all that it was a scam.
