However, our survey confirmed recent literature regarding online recruitment for hard-to-reach populations. In a study conducted by Martinez et al, the researchers acquired tens of thousands of impressions on different Websites such as Facebook and Craigslist and mobile phone apps such as Instagram, Grindr, and Jack’d to recruit HIV-positive gay Latinos . Similarly, our study used various platforms (subreddits) within the large social media Reddit platform to push our survey to populations of interest. After reaching over 100,000 viewers, we received about 200 completed surveys, many of which were of dubious quality or validity. Given that Admon et al used Facebook to recruit a large robust sample of pregnant women through advertisements at very low costs, future research is needed to compare these crowdsourcing platforms and others with more social media sites such as Facebook, Twitter, and Instagram . Furthermore, future studies should use an in-person sample as a baseline to compare the Web-based platforms and determine efficacy.
