Twitter va exiger des nouveaux inscrits qu’ils fournissent une adresse e-mail ou un numéro de téléphone valide.

“Selon la plate-forme, qui a testé en amont le procédé, cela permettrait d’empêcher la création de plus de 50 000 comptes par jour. Si un compte déjà créé est suspecté par Twitter d’être un « bot » malveillant après sa création, la plate-forme pourra également demander à son propriétaire un numéro de téléphone ou une adresse e-mail. Tant qu’il n’aura pas fourni ces éléments, le compte sera en quelque sorte invisibilisé. S’il est abonné à un autre utilisateur, il ne sera pas pris en compte dans le nombre d’abonnés de ce dernier. S’il a retweeté l’un de ses messages, même chose : le retweet ne sera pas comptabilisé. Pour Twitter, cela permettrait d’empêcher que des « bots » se suivent entre eux, faisant ainsi gonfler de manière artificielle leur nombre d’abonnés pour « booster leur crédibilité »”.

“In one particularly brazen example, ads were run promoting both a “Pro-Beyonce Protest Rally” and an “Anti-Beyonce Protest Rally” scheduled for the same time time and place following the controversy over the artist’s performance at the 2016 Super Bowl. The pro-Beyoncé ad was targeted at users designated as having African American behaviors. The anti-Beyoncé ad was targeted narrowly at people who had studied to become a police officer or whose job title matched a list of law enforcement or military titles, including officer, colonel, major general (United States), master sergeant, commander (United States), sergeant, brigadier general, petty officer, chief petty officer, lieutenant commander, squadron leader, 911 dispatcher or rear admiral”.

“After months of pursuing the case, Schneiderman and his team finally got access to documents that allowed them to come to the conclusion that the perpetrators stole as many as 2 million American identities. « The first three words in our Constitution are, ‘We the People.’ The federal rulemaking process is an essential part of our democracy and allows Americans the opportunity to express their opinions on how government agencies decide important regulatory issues. As such, we are concerned about the aforementioned fraudulent activity. We need to prevent the deliberate misuse of Americans’ personal information and ensure that the FCC is working to protect against current and future vulnerabilities in its system. »”

Facebook - Fake

«In its first quarterly Community Standards Enforcement Report, Facebook said the overwhelming majority of moderation action was against spam posts and fake accounts: it took action on 837m pieces of spam, and shut down a further 583m fake accounts on the site in the three months. But Facebook also moderated 2.5m pieces of hate speech, 1.9m pieces of terrorist propaganda, 3.4m pieces of graphic violence and 21m pieces of content featuring adult nudity and sexual activity».

«Epstein’s group asked 661 Americans to pick one of two candidates in an Australian election. Since it was presumed they did not know much about Antipodean politics, the participants were instructed to research them with a Google-type search engine that offered the usual autocomplete suggestions when words were typed in. However, the researchers also varied the search suggestions shown beneath a candidate’s name, including a range of positive and negative words. The results were stark. When participants were later questioned about their voting preferences, changing the ratio of positive to negative suggestions in the autocomplete was shown to be capable of shifting the preferences of undecided voters by nearly 80 per cent — even though participants seemed free to search for any material they wanted».

«DARPA’s MediFor program brings together world-class researchers to attempt to level the digital imagery playing field, which currently favors the manipulator, by developing technologies for the automated assessment of the integrity of an image or video and integrating these in an end-to-end media forensics platform. If successful, the MediFor platform will automatically detect manipulations, provide detailed information about how these manipulations were performed, and reasonoverall integrity of visual media to facilitate decisions regarding the use of any questionable image or video».

«Voters in Pennsylvania, Virginia, and Wisconsin, all states with tight races, were the most targeted. Specifically, voters in Wisconsin were targeted with gun ads about 72 percent more often than the national average. She also found that white voters received 87 percent of all immigration ads. It makes sense that swing states would be more heavily targeted overall leading up to an election. And Kim didn’t analyze the Russians trolls’ targets independently from the other unregulated ads, given the small sample size of 19 groups».

«Les données sont un outil, comme un couteau qui peut être utilisé pour préparer un repas trois étoiles au Michelin ou pour commettre un meurtre. En tant que telles, elles ne sont pas un problème. Mais ce que Cambridge Analytica met au jour est l’échec des législateurs et de la société à mettre des limites à leur utilisation» – Christopher Wylie.
