Étiquette : Twitter (Page 1 of 7)

“Twitter it was looking into why the neural network it uses to generate photo previews apparently chooses to show white people’s faces more frequently than Black faces. Several Twitter users demonstrated the issue over the weekend, posting examples of posts that had a Black person’s face and a white person’s face. Twitter’s preview showed the white faces more often.”

“On Friday, Mr Trump posted on Facebook and Twitter that he would respond to violent protests with military force, saying: “When the looting starts, the shooting starts.” While Twitter slapped a warning on the post and hid it from view for “glorifying violence”, Facebook left the message intact. Over the weekend, Facebook employees contrasted their company’s stance unfavourably with Twitter’s, which last week also labelled two of Mr Trump’s other tweets as potentially misleading.”

“The tool, called LPAuditor (short for Location Privacy Auditor), exploits what the researchers call an « invasive policy » Twitter deployed after it introduced the ability to tag tweets with a location in 2009. For years, users who chose to geotag tweets with any location, even something as geographically broad as “New York City,” also automatically gave their precise GPS coordinates. Users wouldn’t see the coordinates displayed on Twitter. Nor would their followers. But the GPS information would still be included in the tweet’s metadata and accessible through Twitter’s API”.

“But the rest of the world doesn’t even need to clamp down on the alternative web to relegate it to irrelevancy. The reason why these echo chambers are mostly ghost towns, Squirrell says, is that they deprive posters of the one thing that many of them crave: attention. “A huge amount of the culture that these people have is that they want to trigger as many people as possible,” he says. And to do that, you’re better off on the real internet. “If you want to produce something that will eventually get out into the world, 4chan is the place to do it,” Squirrel says.”

“Cette affaire, comme beaucoup d’autres, illustre une nouvelle fois la difficulté qu’a Twitter à modérer son réseau social. Malgré les avalanches d’annonces ces dernières années visant à faire de cette plate-forme un espace de discussion plus « sain », Twitter a échoué à supprimer une menace de mort signalée par la personne ciblée – et n’a réagi que lorsque l’auteur de ce message a fait les gros titres. Malgré les efforts annoncés par Twitter, les messages de haine, les menaces et le harcèlement parviennent à subsister sur le réseau social.”

Twitter Sold Data Access to Cambridge Analytica-Linked Researcher

Cela remonte à avril, mais cela m’avait échappé…

“Twitter sold data access to the Cambridge University academic who also obtained millions of Facebook users’ information that was later passed to a political consulting firm without the users’ consent. Aleksandr Kogan, who created a personality quiz on Facebook to harvest information later used by Cambridge Analytica, established his own commercial enterprise, Global Science Research (GSR). That firm was granted access to large-scale public Twitter data, covering months of posts, for one day in 2015, according to Twitter.”
