A recent from the Grand Island Independent demonstrates this phenomenon. In the article, a physician with the St. Francis Cancer Treatment Center strongly discourages smokers from using e-cigarettes to quit smoking. Instead, he insists that smokers rely only upon FDA-approved drugs.

The policy also states: "We give your information to the people and companies that help us provide, understand and improve the services we offer. For example, we may use outside vendors to help host our website, serve photos and videos, process payments, analyze data, conduct and publish research, measure the effectiveness of ads, or provide search results."

In fact, the subjects had no idea that they were part of an experiment involving artificial manipulation of their news feed for the purposes of potential inducing happiness or sadness as part of a research study. This potential use of their Facebook account is simply not mentioned in the Data Use Policy. The policy states that the information provided by users may be used for research purposes. It also states that the information may be shared with outside vendors to conduct research. However, nowhere does the policy state that users agree to intentional manipulation by Facebook staff for research purposes.

So next time you make a trade online or if you are planning to do so in the future, keep in mind PayPal may be the most secure way of transferring the money, but leave the comment section blank. Or just don’t mention anything about E-Cigs or vaping at all. Better safe than severely sorry. A link to PayPal’s policy
