The use of Facebook can have psychological effects, including feelings of jealousy   and stress,   a lack of attention,  and social media addiction, in some cases comparable to drug addiction.  
Facebook's company tactics have also received prominent coverage, including electricity usage,
 tax avoidance,
 real-name user requirement policies,
 and its involvement in the United States
Due to allowing users to publish material by themselves, Facebook has come under scrutiny for the amount of freedom it gives users, including

Instant Personalization was a pilot program which shared Facebook account information with affiliated sites, such as sharing a user's list of "liked" bands with a music website, so that when the user visits the site, their preferred music plays automatically. The EFF noted that "For users that have not opted out, Instant Personalization is instant data leakage. As soon as you visit the sites in the pilot program (Yelp, Pandora, and Microsoft Docs) the sites can access your name, your picture, your gender, your current location, your list of friends, all the Pages you have Liked—everything Facebook classifies as public information. Even if you opt out of Instant Personalization, there's still data leakage if your friends use Instant Personalization websites—their activities can give away information about you, unless you block those applications individually."

|“||A small fraction of the code that displays Facebook web pages was exposed to a small number of users due to a single misconfigured web server that was fixed immediately. It was not a security breach and did not compromise user data in any way. Because the code that was released powers only Facebook user interface, it offers no useful insight into the inner workings of Facebook. The reprinting of this code violates several laws and we ask that people not distribute it further.||”|

On December 1, Facebook's credibility in regard to the Beacon program was further tested when it was reported that the
|“||When a Facebook user takes a Beacon-enabled action on a participating site, information is sent to Facebook in order for Facebook to operate Beacon technologically. If a Facebook user clicks 'No, thanks' on the partner site notification, Facebook does not use the data and deletes it from its servers. Separately, before Facebook can determine whether the user is logged in, some data may be transferred from the participating site to Facebook. In those cases, Facebook does not associate the information with any individual user account, and deletes the data as well.||”|
The Beacon service ended in September 2009 along with the settlement of a class-action lawsuit against Facebook resulting from the service. 
On September 5, 2006, Facebook introduced two new features called "

In May 2010, Facebook added privacy controls and streamlined its privacy settings, giving users more ways to manage status updates and other information that is broadcast to the public News Feed.  Among the new privacy settings is the ability to control who sees each new status update a user posts: Everyone, Friends of Friends, or Friends Only. Users can now hide each status update from specific people as well.  However, a user who presses "like" or comments on the photo or status update of a friend cannot prevent that action from appearing in the news feeds of all the user's friends, even non-mutual ones. The "View As" option, used to show a user how privacy controls filter out what a specific given friend can see, only displays the user's timeline and gives no indication that items missing from the timeline may still be showing up in the friend's own news feed.
Government and local authorities rely on Facebook and other social networks to investigate crimes and obtain evidence to help establish a crime, provide location information, establish motives, prove and disprove alibis, and reveal communications.
 Federal, state, and local investigations have not been restricted to profiles that are publicly available or willingly provided to the government; Facebook has willingly provided information in response to government subpoenas or requests, except with regard to private, unopened inbox messages less than 181 days old, which require a warrant and a finding of probable cause under federal law.
 An article by Junichi Semitsu published in the Pace Law Review'
 reports that "even when the government lacks reasonable suspicion of criminal activity and the user opts for the strictest privacy controls, Facebook users still cannot expect federal law to stop their 'private' content and communications from being used against them. "

National Journal Daily claims "Facebook is facing new scrutiny over its decision to automatically turn on a new facial recognition feature aimed at helping users identify their friends in photos".
 Facebook has defended the feature, saying users can disable it.

In August 2011, the Irish Data Protection Commissioner (DPC) started an investigation after receiving 22 complaints by europe-v-facebook.org, which was founded by a group of Austrian students.
 The DPC stated in first reactions that the Irish DPC is legally responsible for privacy on Facebook for all users within the
The group 'europe-v-facebook.org' made access requests at Facebook Ireland and received up to 1,222 pages of data per person in 57 data categories that Facebook was holding about them,  including data that was previously removed by the users.  Despite the amount of information given, the group claimed that Facebook did not give them all of its data. Some of the information not included was "likes", data about the new face recognition function, data about third party websites that use "social plugins" visited by users and information about uploaded videos. Currently the group claims that Facebook holds at least 84 data categories about every user.

In early November 2015, Facebook was ordered by the Belgian Privacy Commissioner to cease tracking non-users, citing European laws, or else risk fines of up to £250,000 per day.  As a result, instead of removing tracking cookies, Facebook prevents non-users from seeing any material on Facebook, including publicly-posted content. Arguing that the cookies provided better security, Facebook said in a statement: "We're disappointed we were unable to reach an agreement and now people will be required to log in or register for an account to see publicly available content on Facebook."  
Social networks, like Facebook, can have a detrimental effect on marriages, with users becoming worried about their spouse's contacts and relations with other people online, leading to marital breakdown and divorce.  According to a 2009 survey in the UK, around 20 percent of divorce petitions included some kind of reference to Facebook.     Facebook has given us a new platform for interpersonal communication. Researchers proposed that high levels of Facebook use could result in Facebook-related conflict and breakup/divorce.  Previous studies have shown that romantic relationships can be damaged by excessive internet use, Facebook jealousy, partner surveillance, ambiguous information, and online portrayal of intimate relationships.      Excessive internet users reported having greater conflict in their relationships. Their partners feel neglected and there's lower commitment, lower feelings of passion and intimacy in the relationship. According to the article, researchers suspect that Facebook may attribute to an increase in divorce and infidelity rates in the near future due to the amount of accessibility to connect with past partners. 
By statistics, 63% of Facebook profiles are automatically set "visible to the public" meaning anyone can access the profiles that users have updated. Facebook also has its own built in messaging system that people can send message to any other user, unless they have disabled the feature to "from friends only". Stalking is not only limited to
The notion that people are very much aware that they are being surveiled on websites, like Facebook, and use the surveillance as an opportunity to portray themselves in a way that connotes a certain lifestyle—of which, that individual may, or may not, distort how they are perceived in reality. 
In an effort to surveil the personal lives of current, or prospective employees, some employers have asked employees to disclose their Facebook log-in information. This has resulted in the passing of a bill in New Jersey making it illegal for employers to ask potential or current employees for access to their Facebook accounts.  Although, the U.S government has yet to pass a national law protecting prospective employees and their social networking sites, from employers, the fourth amendment of the US constitution can protect prospective employees in specific situations.   Lots of companies look at Facebook profiles of job candidates looking for reasons to not hire them. According to a survey of hiring managers by CareerBuilder.com, the most common deal breakers they found on Facebook profiles include references to drinking, poor communication skills, inappropriate photos, and lying about skills and/or qualifications.

Some research    on Facebook in higher education suggests that there may be some small educational benefits associated with student Facebook use, including improving engagement which is related to student retention.  2012 research has found that time spent on Facebook is related to involvement in campus activities.  This same study found that certain Facebook activities like commenting and creating or RSVPing to events were positively related to student engagement while playing games and checking up on friends was negatively related. Furthermore, using technologies such as Facebook to connect with others can help college students be less depressed and cope with feelings of loneliness and homesickness. 
As of February 2012, only four published peer-reviewed studies have examined the relationship between Facebook use and grades.     There is considerable variance in the findings. Pasek et al. (2009)  found there was no relationship between Facebook use and grades. Kolek and Saunders (2008)  found that there were no differences in overall grade point average (GPA) between users and non-users of Facebook. Kirschner and Karpinski (2010)  found that Facebook users reported a lower mean GPA than non-users. Junco's (2012)  study clarifies the discrepancies in these findings. While Junco (2012)  found a negative relationship between time spent on Facebook and student GPA in his large sample of college students, the real-world impact of the relationship was negligible. Furthermore, Junco (2012)  found that sharing links and checking up on friends were positively related to GPA while posting status updates was negatively related. In addition to noting the differences in how Facebook use was measured among the four studies, Junco (2012)  concludes that the ways in which students use Facebook are more important in predicting academic outcomes.
The term phishing is one kind of online fraud in which criminals try to trick people into revealing passwords, credit card information, and other sensitive information. Phishing takes the form of a message or Wall post that appears to come from someone on the user's Friend List but in actuality the message was sent by phishers using the friend's login information. The phishers are hoping the user takes the bait resulting in the phishers gaining access to the Facebook user's account . Soon afterwards, the user's other friends will start getting phishing messages from what appears to be from the Facebook user. The point of the post is to get the Facebook user to visit a website with viruses and malware.
