Meant to post this from one of underlying documents:
Meta earns $3.5B ever six months in "higher legal risk" revenue from scams, and that such amount is could be the cumulative "outside order of magnitude" for fines from regulators for accepting scam ads.

This is terrible news, as is the original decision to fold Teen Vogue -- it consistently did some of the best culture reporting on social media of any outlet, period.
Great respect to those who stood up on behalf of their newsrooms.

New: Conde Nast fired four employees who were among a group that confronted the company's head of human resources on Wednesday over the decision to fold Teen Vogue into Vogue/recent cuts. Employees who were fired included journalists from the New Yorker, Wired, and Bon Appétit.

FACEBOOK MARKETPLACE AND MY FEET: A MYSTERY
My wife wanted to sell a mirror, so I listed it on Facebook Marketplace this weekend. I neglected to wear shoes for the photo.
I have since received seven offers: two for the mirror, and five for acts involving my feet. I'm now curious what's going on.

I would gladly read a followup on this focused entirely on IRBs. I've been surprised by how often researchers say they could never got approval to run tests mimicking the sort of interventions that major platforms undertake on far larger populations as a matter of course on a daily basis.

This recent preprint on tech industry influence over external research is compelling. Beyond documenting the low rate of industry-funded researchers actually disclosing that fact, the paper points out that journals have routinely waived IRB review for industry work.

1. We ( @jbakcoleman.bsky.social, @cailinmeister.bsky.social, @jevinwest.bsky.social, and I) have a new preprint up on the arXiv.
There we explore how social media companies and other online information technology firms are able to manipulate scientific research about the effects of their products.

Meta researchers found that teens who report that Instagram regularly made them feel bad about their bodies saw significantly more “eating disorder adjacent content” than those who did not, according to an internal document reviewed by Reuters.

Four years ago, pre GenAI, someone showed me some stunning photos of ravens they'd taken. Among the most beautiful wildlife portraits I've seen. And they refused to put them even on a website because they didn't "want a tech company to steal them."
I rolled my eyes. I think about that now and then.

In case anyone thought ICE shooting at journalists was just an LA thing. Or that they'd cut it out after repeated warnings from judges. Nope. More of the same in Chicago.
Took fire to the face. ICE definitely isn’t aiming at ground and firing at people’s heads again.

Instagram has long talked up its efforts to filter out eating-disorder-related content from young users' feeds and redirect teenagers who are binging on it. External testing, confirmed by documents reviewed by Reuters, suggests those classifiers don't work well.

Instagram’s teen safety features are flawed, researchers say
Numerous safety features that Meta has said it has implemented to protect young users on Instagram over the years do not work well or, in some cases, don't exist, according to a report from child-safety advocacy groups that was corroborated by researchers at Northeastern University.

If you accept $50,000 in a Cava takeout bag from some FBI agents who are posing as businessmen and then the investigation gets called off, does that just mean you’re just up $50k?
This is not political commentary. I would like to know the answer to the hypothetical here.

This feels like the early days of AI's use in scam compounds. Asking a bot to find one or two personalized hooks from someone's social media feed then make a run at getting them engaged before passing off the hot leads to humans seems real straightforward.
