Facebook endured a staggering number of scandals and controversies in 2018 — here they all are

• January 4th: CEO Mark Zuckerberg promises that he will try and fix Facebook's problems in 2018.
• 11th: Facebook announces sweeping changes to its algorithm to prioritize content from friends and family, as well as "meaningful interactions." The change has the consequence of decimating many media companies' traffic, forcing at least one to close the following month.
• 25th: Billionaire philanthropist and investor George Soros slams Facebook (and Google) as a "menace" to society and "obstacles to innovation" in a blistering speech at the World Economic Forum in Davos. Facebook will go on to surreptitiously investigate Soros' motivations and attempt to discredit him and fellow critics in a PR campaign which will ultimately backfire extremely badly — but more on that later.

• February 2nd: Wired publishes an exhaustive investigation looking back over 2016 and 2017, "the two years that shook Facebook — and the world," and how execs came to reckon with Facebook's unprecedented role in the political sphere. In hindsight, this retrospective now seems a tad premature. 

• March 12th: UN experts investigating genocide in Myanmar point the finger at Facebook for its role in spreading hate speech in the country. Further investigations and reports in the months ahead would reveal the true extent of the social network's role in inflaming ethnic tensions and spreading incitements to violence in the country. 
• 17th: This is where Facebook's privacy nightmare begins — the day that The Observer publishes the first bombshell report into how political research firm Cambridge Analytica misappropriated tens of millions of users' data. It's a revelation that snowballs into an unprecedented crisis for the company, sparking intense regulatory scrutiny and an avalanche of other revelations, the reverberations of which are still being felt nine months later.
• 20th: WhatsApp cofounder and former Facebook employee Brian Acton calls for people to delete their Facebook accounts, tweeting: "It is time. #deletefacebook."
• 24th: Facebook comes under fire over revelations that it has been collecting SMS and call data of Android users, unbeknownst to them. The company responds that users consented to the data collection, but the outrage indicates that many people clearly had no idea it was happening.
• 29th: An explosive 2016 memo written by Facebook exec Andrew "Boz" Bosworth leaks to BuzzFeed News. In it, Boz defends Facebook's growth-at-any-cost mentality, even if it meant people died because of Facebook's apps. He later claimed he was trying to be provocative and didn't believe what he had written, even when he wrote it.

• April 4th: Facebook's chief technology officer Mike Schoepfer revises upwards the number of people believed to have been affected by the Cambridge Analytica scandal, up to 87 million. And he makes another, deeply unsettling admission: "Most" of Facebook's two billion users' data has likely been separately scraped by "malicious actors" in an unrelated breach. Zuckerberg subsequently tells reporters: "It is reasonable to expect that if you’ve had that setting on in the last several years that someone has accessed your information."
• 5th: Mark Zuckerberg finds himself in a spot of hot water after a TechCrunch report finds that messages sent by the CEO to other users have been quietly deleted from users' inboxes after the fact, and without informing them — a feature not available to normal Facebook users.
• 10th, 11th: Zuckerberg testifies before Congressional committees about Cambridge Analytica, Russian influence campaigns, allegations of anti-conservative bias, and a number of other subjects.
• 24th: For the first time, Facebook officially publishes its full "Community Standards" — the rules for what will get people banned from the social network. However, they had previously leaked online.
• 30th: Jan Koum, one of the cofounders of messaging app WhatsApp, quits Facebook, reportedly due to concerns over the company's approach to privacy and encryption.

• May 1st and 2nd: Facebook holds its annual F8 developer conference, and ends a moratorium of app and bot approvals for its platform it had imposed in the immediate aftermath of the Cambridge Analytica news, disrupting developers.
• 2nd: Facebook commits to conducting a civil rights audit, led by former ACLU director Laura Murphy. It also agrees to a review examining allegations of anti-conservative bias at the company. 
• 8th: Facebook has a significant reshuffle of its senior executive teams, re-organiing how its core apps and products are managed. It is, Recode reports, the "biggest executive shuffle in company history."
• 24th: Facebook launches its political ad archive, a searchable database of political advertisements that have run on the social network, as it revamps how it vets political ads in an attempt to avoid repeating the mistakes of 2016. The company attracts criticism over its classification of ads by news organisations about political news stories as "political ads," which some in the media argued showed a fundamental misunderstanding of what journalism is. News stories are finally exempted from the archive in November.
• 25th: GDPR, the European Union's tough new data protection regulation, comes into effect. Privacy activists immediately file complaints against Facebook and other tech giants.

• June 3rd: The New York Times reveals how Facebook struck deals with smartphone makers that granted the companies access to significant amounts of users' data. Partners included Apple, Amazon, Samsung, and Microsoft, and the paper reported the deals "raise concerns about the company’s privacy protections and compliance with a 2011 consent decree with the Federal Trade Commission."
• 7th: Facebook discloses that a bug affecting 14 million people in May meant that private status updates shared with friends were also publicly viewable. It's just one of many privacy-control issues Facebook grapples with throughout the year.
• 11th: Business Insider reported that Elliot Schrage, the company's head of policy and communications, apologised to an investor after she accused him of making a sexist remark to her.
• 20th: Facebook-owned Instagram hits a major milestone: It now has one billion monthly active users.

• July 18th: Recode publishes an interview between Mark Zuckerberg and Kara Swisher in which the CEO defends the presence of Holocaust deniers on Facebook because they might not be "intentionally getting it wrong." Amid a firestorm of criticism, Zuckerberg, who is Jewish, clarifies that he "personally find[s] Holocaust denial deeply offensive, and I absolutely didn't intend to defend the intent of people who deny that."
• 25th: After announcing disappointing financial results and predicting a significant growth slowdown in the years ahead, Facebook’s stock price plummets. In the 90 minutes between announcing its results and the end of a conference call with analysts, it drops by more than 20%, wiping out $150 billion in market value — a new record for the stock market.

• August 6th: Facebook moves to ban conspiracy theorist Alex Jones. The notorious conspiracy theorist behind InfoWars is slapped with a 90-day ban on his personal accounts, and multiple associated pages are taken down. Activists had called for the tech companies to stop enabling Jones for months, but Facebook and its peers only scrambled to take action after Apple decided to ban InfoWars and related podcasts from the iTunes podcast directory.
• 15th: An investigation from Reuters finds that Facebook's moderation efforts in Myanmar were inadequate, with hate speech and incitements to violence and genocide still proliferating on the site despite Zuckerberg's promises to US lawmakers in April to crack down on the problem. 
• 21st: Facebook says it has detected Iran-backed groups pretending to be news organisation to spread influence opinions and launch cyber-attacks.

• 21st: New research links the use of Facebook in Germany to violent anti-refugee attacks.

• September 4th: New reports on the same day from The New York Times and BuzzFeed News shed more light on how Facebook can fuel political violence around the world, in Libya and the Philippines respectively. In the former case, armed groups used Facebook to identify critics and spread propaganda or misinformation. In the Philippines, meanwhile, Facebook is used to spread hoaxes about the President Duterte's rivals, fuel fake news, and boost his bloody drug war.  
• 5th: Sheryl Sandberg testifies to Congress alongside Twitter CEO Jack Dorsey about misinformation and other subjects.
• 16th: Business Insider reports on how a tool Facebook built to help facilitate blood donations in India and elsewhere is fueling an illegal and dangerous black market for human blood in the country.

• 26th: WhatsApp cofounder Brian Acton — who earlier in the year tweeted "#deletefacebook" — gives a scathing interview to Forbes about his former employer.

• 26th: Gizmodo reveals that Facebook has been using phone numbers provided by users for two-factor authentication, a highly recommended security measure, to subsequently target them with advertisements.

The Irish data regulatory body is now investigating, and Facebook could be fined up to $1.6 billion over the breach.

• October 4th: In late September, Facebook's policy chief Joel Kaplan attends a congressional hearing for Brett Kavanaugh, now a Supreme Court Justice. Employees exploded in outrage, with the internal revolt finally bursting into public view with news reports in early October. Some employees said they felt uncomfortable working with Kaplan, and that his attendance was "inappropriate."
• 7th: The first round of Brazil's presidential election is held amid a backdrop of widespread hoaxes and misinformation being spread on WhatsApp in support of far-right candidate Jair Bolsonaro, who ultimately wins the presidency.

• 16th: A group of marketers sue Facebook alleging ad fraud, claiming it knew of measurement issues and discrepancies in its data for more than a year before reporting it to advertisers. They also allege the discrepencies were by as much as 900% — far more than the 60-80% previously disclosed.

• 14th: The New York Times drops a bombshell report into how Facebook's leadership attempted to deflect criticism as its scandals mounted throughout the year. The investigation opens COO Sheryl Sandberg up to unprecedented scrutiny over her role in handling operations, and it reveals that Facebook, via opposition research firm Definers, attempted to smear its critics by linking them to George Soros — a line of attack that has been labeled anti-Semitic.
