Do not fill this in! ==== Shadow profiles ==== A "[[shadow profile]]" refers to the data Facebook collects about individuals without their explicit permission. For example, the [[Facebook like button#Tracking|"like" button]] that appears on third-party websites allows the company to collect information about an individual's internet browsing habits, even if the individual is not a Facebook user.<ref name="verge shadow profiles">{{cite web|url=https://www.theverge.com/2018/4/11/17225482/facebook-shadow-profiles-zuckerberg-congress-data-privacy|title=Shadow profiles are the biggest flaw in Facebook's privacy defense|last=Brandom|first=Russell|date=April 11, 2018|website=[[The Verge]]|access-date=June 28, 2019}}</ref><ref>{{cite web|title=How Facebook can have your data even if you're not on Facebook|work=[[USA Today]]|access-date=April 13, 2018|url=https://www.usatoday.com/story/tech/columnist/baig/2018/04/13/how-facebook-can-have-your-data-even-if-youre-not-facebook/512674002/}}</ref> Data can also be collected by other users. For example, a Facebook user can link their email account to their Facebook to find friends on the site, allowing the company to collect the email addresses of users and non-users alike.<ref>{{cite web|url=https://gizmodo.com/how-facebook-figures-out-everyone-youve-ever-met-1819822691|title=How Facebook Figures Out Everyone You've Ever Met|last=Hill|first=Kashmir|date=November 7, 2017|website=[[Gizmodo]]|access-date=June 28, 2019}}</ref> Over time, countless data points about an individual are collected; any single data point perhaps cannot identify an individual, but together allows the company to form a unique "profile". This practice has been criticized by those who believe people should be able to opt-out of involuntary data collection. Additionally, while Facebook users have the ability to download and inspect the data they provide to the site, data from the user's "shadow profile" is not included, and non-users of Facebook do not have access to this tool regardless. The company has also been unclear whether or not it is possible for a person to revoke Facebook's access to their "shadow profile".<ref name="verge shadow profiles" /> Summary: Please note that all contributions to Christianpedia may be edited, altered, or removed by other contributors.
