"According to a report by Sophos, malware and spam are on the rise on social networks such as Twitter, MySpace, Facebook and LinkedIn. In the last year, 57% of users report they have been spammed via social networking sites, an increase of 70.6% compared to last year. Furthermore, 36% of users claim they've been sent malware via social networking sites, which is a rise of 69.8% from last year. On the other hand, CEOs of companies are concerned that their employees' usage of social networks is posing a security risk for their company. Sophos has surveyed more than 500 organizations, discovering that 72% of them think social networks are a danger for their companys, with 60% of them tagging Facebook as the biggest security risk, followed by MySpace, Twitter and LinkedIn. Graham Cluley, senior technology consultant for Sophos, says that Facebook is the biggest threat because it's the biggest social network out there, but he also places some of the blame on Facebook's own privacy rules. "When Facebook rolled-out its new recommended privacy settings late last year, it was a backwards step, encouraging many users to share their information with everybody on the internet," he says. Interestingly enough (and contrasted to some of the reports we've seen lately), Cluley thinks that simply barring access to Facebook is not the solution. "Social networks can be an essential part of the business mix today," he says, "and the answer is not to bar staff from participating in them but to apply some 'social security' instead.""

"But users began to spot flaws in the feature over the weekend. The first to highlight the issue was PhD student Colin Madland, who discovered the issue while highlighting a different racial bias in the video-conference software Zoom. When Madland, who is white, posted an image of himself and a black colleague who had been erased from a Zoom call after its algorithm failed to recognise his face, Twitter automatically cropped the image to only show Madland."

"Twitter has been flooded with nuisance posts designed to obscure news of the coronavirus lockdown protests in China, in an apparent state-directed attempt to suppress footage of the demonstrations. Chinese bot accounts - not operated by humans - are being used to flood the social networking service with adverts for sex workers, pornography and gambling when users search for a major city in the country, such as Shanghai or Beijing, using Chinese script."

"With news that the 15 million Twitter users in the UK can now be targeted at individual postcode levels, the micro-blogging platform is selling its advertising opportunities as ultra-geographically precise, and therefore ultra-cost effective. "The key benefit of geo-targeting is that it enables advertisers, or in this case political parties, the ability to reach users in specific regions, metropolitan areas and now postcodes," Twitter said in a blog post. "

"But the bigger problem with things like public tweets is that no-one knows what information can be derived from them, either now or in the future. I write as a data analyst who's done a fair bit of work with this kind of material. What follows are a few techniques that aren't at all obvious to the average Twitter user. They go far beyond reading the surface text (or metadata) of an individual tweet. And these are just some of the techniques currently used to mine this data, ethically or unethically, legally or illegally."

"The social network, which did not oppose the application, has until mid-January to comply. The parody accounts, @Wetherspoon__UK and @SpoonsTom, have tens of thousands of followers each on the social network, and tweet a mixture of fake updates about Wetherspoon's pubs and replies to users who mistakenly believe they are contacting the real company."

"The new tools appear to allow Twitter users to share images with text overlays, stickers, and other modifications. Twitter's existing tools merely allow people to crop images or run them through filters that greatly change their appearance, whether it's by upping the contrast or making them look like old Polaroid shots."

"Twitter's image cropping algorithm prefers younger, slimmer faces with lighter skin, an investigation into algorithmic bias at the company has found. The finding, while embarrassing for the company, which had previously apologised to users after reports of bias, marks the successful conclusion of Twitter's first ever "algorithmic bug bounty"."

"But, for a growing number of users - and mental health experts - the very positivity of Instagram is precisely the problem. The site encourages its users to present an upbeat, attractive image that others may find at best misleading and at worse harmful. If Facebook demonstrates that everyone is boring and Twitter proves that everyone is awful, Instagram makes you worry that everyone is perfect - except you."

"Twitter claims a 90 percent accuracy rate for the clever techniques it uses to learn the gender of any given user. Glenn Fleishman reports on a the company's disconcerting new analytics tools, the research behind them, and how large a pinch of salt they come with."

"The new policy is a major shift in Twitter's efforts to balance its ideological commitment to free expression with user demands for improved enforcement of rules against harassment, hate speech and other toxic behavior."

"Users post violent and hateful content to Facebook and Twitter all the time, they argued - and no one was demanding those platforms get the boot from the app stores."

""The abhorrent racist abuse directed at England players last night has absolutely no place on Twitter," the social network said on Monday morning. A Facebook spokesperson said similarly: "No one should have to experience racist abuse anywhere, and we don't want it on Instagram." But the statements bore little relation to the experience of the company's users. On Instagram, where thousands left comments on the pages of Marcus Rashford, Bukayo Saka and Jadon Sancho, supportive users who tried to flag abuse to the platform were surprised by the response."

"The world's biggest social networks say racism isn't welcome on their platforms, but a combination of poor enforcement and weak rules have allowed hate to flourish."

"To coincide with the launch, the campaign has released research by Demos revealing the huge scale of social media misogyny. The study monitored the use of the words "slut" and "whore" by UK Twitter users over three weeks from the end of April. It found that 6,500 individuals were targeted by 10,000 aggressive and misogynistic tweets in that period."

"Sophie Bishton, a junior doctor, was "fed up with traditional learning and being talked at all the time" and so founded the Twitter finals revision group (known as twitfrg) in October 2012. Users are invited to participate in a scenario in real time. Prior to the event, revision notes related to the case are made available online. At a prearranged time, a tweet is sent marking the beginning of the scenario. "

"This is what's about to happen with twitpic, for years the go-to service for posting photos to Twitter, and the people in charge appear to be doing what they can to prevent the Internet Archive preserving the database and to deny users functional archive access to their own uploads. "

"Gmail users are under attack in a gigantic phishing operation that's spreading like wildfire across the internet right now. People took to Twitter to report receiving an email that looks like an invitation to join a Google Doc from someone they know. But when you click on the link to open the file, you are directed to grant access to an app that looks like Google Docs but is actually a program that sends spam emails to everyone you've emailed, according to a detailed outline of the attack on Reddit.
