Twitter’s new owner Elon Musk is further gutting the teams that battle misinformation on the social media platform as outsourced moderators learned over the weekend they were out of a job.

Twitter and other big social media firms have relied heavily on contractors to track hate and enforce rules against harmful content.

But many of those content watchdogs have now headed out the door, first when Twitter fired much of its full-time workforce by email on Nov. 4 and now as it moves to eliminate an untold number of contract jobs.

Melissa Ingle, who worked at Twitter as a contractor for more than a year, was one of a number of contractors who said they were terminated Saturday. She said she’s concerned that there’s going to be an increase in abuse on Twitter with the number of workers leaving.

“I love the platform and I really enjoyed working at the company and trying to make it better. And I’m just really fearful of what’s going to slip through the cracks,” she said Sunday.

Ingle, a data scientist, said she worked on the data and monitoring arm of Twitter’s civic integrity team. Her job involved writing algorithms to find political misinformation on the platform in countries such as the U.S., Brazil, Japan, Argentina and elsewhere.

Ingle said she was “pretty sure I was done for” when she couldn’t access her work email Saturday. The notification from the contracting company she’d been hired by came two hours later.

“I’ll just be putting my resumes out there and talking to people,” she said. “I have two children. And I’m worried about being able to give them a nice Christmas, you know, and just mundane things like that, that are important. I just think it’s particularly heartless to do this at this time.”

Content-moderation expert Sarah Roberts, an associate professor at the University of California, Los Angeles who worked as a staff researcher at Twitter earlier this year, said she believes at least 3,000 contract workers were fired Saturday night.

Twitter hasn’t said how many contract workers it cut. The company hasn’t responded to media requests for information since Musk took over.

At Twitter’s San Francisco headquarters and other offices, contract workers wore green badges while full-time workers wore blue badges. Contractors did a number of jobs to help keep Twitter running, including engineering and marketing, Roberts said. But it was the huge force of contracted moderators that was “mission critical” to the platform, said Roberts.

Cutting them will have a “tangible impact on the experience of the platform,” she said.

Musk promised to loosen speech restrictions when he took over Twitter. But in the early days after Musk bought Twitter for $44 billion in late October and dismissed its board of directors and top executives, the billionaire Tesla CEO sought to assure civil rights groups and advertisers that the platform could continue tamping down hate and hate-fueled violence.

That message was reiterated by Twitter’s then-head of content moderation, Yoel Roth, who tweeted that the Nov. 4 layoffs only affected “15% of our Trust & Safety organization (as opposed to approximately 50% cuts company-wide), with our front-line moderation staff experiencing the least impact.”

Roth has since resigned from the company, joining an exodus of high-level leaders who were tasked with privacy protection, cybersecurity and complying with regulations.

Australian researchers have identified 1,500 additional locations across the country that could be used as pumped storage hydropower facilities. They have said it should reduce Australia’s reliance on fossil fuels.

Academics at the Australian National University have said pumped storage hydropower is a “low-cost, mass storage option” that could help Australia reach its emissions reduction targets.

Emeritus Professor Andrew Blakers at the university’s College of Engineering, Computing and Cybernetics told VOA the process involves transferring water between two reservoirs or lakes at different elevations.

He said water is pumped to the higher reservoir when there are plentiful supplies of wind and solar energy. The water is then released at night, or at other times when it is not windy or sunny, maximizing the use of the stored energy in the reservoirs.

“We have two reservoirs; one at the top of a hill and the other down in a valley connected with a pipe or tunnel,” he said. “On sunny and windy days, the pump turbine pumps water uphill to the upper reservoir and then in the middle of the night the water is allowed to come back down through the turbine to recover the energy that was stored. So, the same water goes up and down between the two reservoirs for 100 years. So, if you want large-scale storage, you go to pumped hydro.”

Researchers studied the area near every reservoir in Australia looking for a potential site for another reservoir that could be used as pumped storage hydropower.

They identified 1,500 locations that could help Australia store the energy it generates from wind and solar projects.

Blakers says Australia is becoming a world leader in the field.

“All Australian governments and companies are focused on very rapid construction of solar and wind, and equally rapid construction of new transmission to bring the new power to the cities, and pumped hydro and battery storage to balance the variable solar and wind. Australia is the global pathfinder. We are leading in every department,” he said.

Australia has a target of producing 82% of its electricity from renewable sources by 2030.

Because of the country’s heavy reliance on coal and natural gas, it has been one of the world’s worst emitters of greenhouse gases, per capita.

Those fossil fuels continue to generate much of Australia’s electricity, but researchers believe that the country’s path toward a cleaner energy future is well underway.

The Australian National University study released Friday follows the team’s identification of 530,000 potential pumped-storage hydro sites across the world.
