British lawmakers want Alexander Nix, the suspended chief executive of Cambridge Analytica, to return to Parliament for additional questioning in its fake news inquiry. The Parliament's probe led to disclosures that Facebook had allowed Cambridge Analytica unauthorized access to up to 50 million user records, igniting a firestorm over user data privacy and possible U.S. voter manipulation.

YouTube has announced that it will ban videos related to the sale or assembly of firearms, as well as certain gun accessories including bump stocks. Under the new rules, all videos that show how to construct or even repair a firearm are banned -- even those from long-established YouTube channels. The new policy also bans videos that show how to reload ammunition.

CEO Mark Zuckerberg broke Facebook's mysterious silence following news of investigations into Cambridge Analytica's access to personal data belonging to 50 million Facebook users. Facing the wrath of everyone from U.S. and European regulators to shareholders, customers and employees, Zuckerberg conceded that Facebook must make several changes if it expects to be taken seriously in the future.

Many Facebook members reportedly have shuttered their accounts following reports that Cambridge Analytica, a voter profiling company working for Donald Trump's presidential campaign, harvested data from 50 million users, unbeknownst to them. Indignation over Facebook's role in the data leak has mushroomed, and some users have taken to Twitter to announce their liberation from the social network.

EU, UK and U.S. officials have ratcheted up the pressure on Facebook over a user data scandal that threatens to engulf the company. The president of the European Parliament, Antonio Tajani, summed up the stakes in a tweet on Tuesday: "Facebook needs to clarify before the representatives of 500 million Europeans that personal data is not being used to manipulate democracy."

The scene in A Few Good Men with Jack Nicholson going off on handling the truth has been coming to mind way too often of late. Sadly, this is the world we are living in right now, and social media is at the heart of it. I recently noticed a headline that implied a lot of people had taken exception to something Gal Gadot tweeted about Stephen Hawking.

YouTube intends to ramp up its efforts to combat conspiracy mongers, perhaps in response to the rash of conspiracy videos that trended following the school shooting in Parkland, Florida, last month. Among other things, YouTube will supply links to relevant Wikipedia pages and other credible websites to provide viewers with a counter narrative, according to CEO Susan Wojcicki.

Facebook has millions of users in the European Union, and a German court recently ruled against the company in a case involving its Privacy Policy. Few ever read privacy policies except judges, who must examine them when challenges arise. The new EU General Data Protection Regulations, which go into effect on May 25, will make things even more complicated. If you have any customers who are EU residents, the new GDPR will impact you.

Americans have been targeted on social media by Russian agents on a mission to harvest personal information. The agents pretended to work for organizations promoting African-American businesses as a ruse to obtain personal information from black business owners during the 2016 presidential election campaign. Using names like "BlackMattersUS," the agents set up hundreds of social media accounts.

Adam Smith famously referred to "the invisible hand" of the free market in his landmark book The Wealth of Nations, and with that made himself one of the very first political economists. Smith's observation was so on point that most of us assume markets run through the agency of individuals pursuing their enlightened self-interests, which helped drive the evolution of CRM as a tracking tool.

Facebook has come under fire after posing a survey question on how it should deal with predatory sexual behavior against children over the weekend. Survey participants were asked whether sexual predators should be allowed to request photographic images from 14-year-old girls online. Further, users were queried about how Facebook should handle such a request if it learned about it.

Vero, a relatively unknown social network, has been enjoying a surge in user engagement in recent weeks, a trend that may be tied to growing user discontent over recent changes to Instagram's algorithm, along with an assortment of other objections that have been driving users away from the leading social platforms. Vero has rapidly moved up in the App Store and Google Play rankings.

Conservatives on Twitter have been fulminating over their losses of followers measured in the thousands, a consequence of the network's unannounced lockout earlier this week of suspected bot accounts. Among those objecting to the move are conspiracy theorist Michael Flynn Jr., white supremacist Richard Spencer, Infowars editor Paul Joseph Watson, and NRA TV host Dan Bongino.

As beneficial as AI can be, it has its dark side, too. That dark side is the focus of a new 100-page report. AI will be used by threat actors to expand the scale and efficiency of their attacks, it predicts. They will employ it to compromise physical systems and to broaden their privacy invasion and social manipulation capabilities. Novel attacks are to be expected.

Within an hour of the shooting at a Florida High School last week, divisive messages began pouring out of Twitter accounts believed to be controlled by Russia. At a rapid speed, messages reportedly began flooding Twitter using popular hashtags to exploit the rampage by a lone gunman with an assault rifle at the Marjory Stoneman Douglas High School in Parkland, Florida.

Google has rolled out a developer preview of its new AMP story format, which is designed to give content publishers an easy way to deliver news and information on mobile devices with visually rich, tap-through stories.

A group of former Facebook, Google and Mozilla executives have joined forces to establish the Center for Humane Technology, a new organization dedicated to combating the growing problem of addictive behavior among social media users. The new center, along with the children's advocacy group Common Sense, has announced a campaign to help change the social media model.

The social media industry may have to struggle to rehydrate in light of some surprising and troubling metrics Facebook released on Wednesday. In addition to a pause in user growth, there have been signs that user engagement may have reversed course. The decline may have something to do with Facebook's efforts to recover from accusations that it has provided fertile ground for fake news.

Facebook once again has found itself at the center of a media storm, following Mark Zuckerberg's recent announcement of plans to shift its focus away from news and business content and toward interactions between friends and family. The shift follows more than a year of heavy criticism directed against Facebook, including blame for failing to combat fake news during the 2016 presidential election.

A recent article on the institutionalized sexual exploitation going on in tech companies is eye-opening. It comes on top of the realization that social media companies like Facebook are destroying the U.S., and former Facebook executives have been dissociating themselves from the company. Further, news recently broke of a big, industry-wide security problem.

SMBs should "be proactive and ready to help [customers] right at the moment they need it," said Linda Crawford, CEO of Helpshift. Companies must streamline support systems to resolve issues faster and more efficiently, she said. An up-to-date knowledge base enables instant self-service, "but SMBs must also offer channels for customers to communicate directly with support agents."

Germany on Monday began enforcing its new Network Enforcement Act, or NetzDG, which imposes a fine of up to $60 million on social media networks that fail to remove hate-inciting posts promptly. The controversial law, adopted in mid 2017, is designed to help combat hate and fake news at a time when ISIS-linked terror and anti-immigrant extremism have been on the rise in Germany.

Is social media evolving into an antisocial medium? Days after one of its former execs argued that the answer is yes, Facebook published a post addressing the issue. "I think we have created tools that are ripping apart the social fabric of how society works," said Chamath Palihapitiya, who once served as vice president for growth at Facebook. There is a lack of civil discourse, he added.

Snap aims to combat fake news on Snapchat by separating content from professional creators from postings by friends and family. Stories and Chats from friends will appear on the left side of the camera, while Stories from content creators, publishers and other members of the community will appear on the right side. Snapchat aims to disentangle "social" from "media," noted Snap CEO Evan Spiegel.

This is the question that keeps me up at night after seeing the news of Russian influence through social media, and the rapid rise of road deaths due to smartphone use. I wonder if the executives in these firms understand not only that dead customers don't generate revenue, but also that some of the victims could end up being their own kids, spouses or parents.

Facebook on Tuesday announced that it was preparing a plugin to its popular Messenger platform that will allow a website's visitors to chat with a human or bot without leaving the location. Customer Chat is one of a number of changes in the version 2.2 update of Messenger platform revealed at the Web Summit in Lisbon, Portugal. The chat plugin will be available on desktop and mobile devices.

A new feature that Facebook recently has been testing in a handful of countries could hurt publishers everywhere if it should roll out globally. The feature removes users' Liked pages from their main News Feed and aggregates them in a separate space called "Explore." In the six countries where Facebook has been testing the idea, traffic to news outlets reportedly has dropped 60-80 percent.

PayPal has announced the immediate availability of its peer-to-peer payment service on Facebook Messenger, making it easy to exchange money between friends and family.

Social media platforms like Facebook, Twitter and YouTube may pose a threat to American democracy, suggests a new report from The Omidyar Group. The report follows recent disclosures about targeted dark post advertising, fake news and other abuses propagated by Russian troll farms during the 2016 election. Among the questions the report raises is whether the U.S. government may need to step in.

Social media influencer advertising has become a major factor in e-commerce. Marketers of both big and small brands long have committed large chunks of their advertising budgets to endorsements by well-known personalities. Social media influencer campaigns are based on that tried-and-true formula, but the implication is that the endorsements are voluntary.
