We got Meta’s “general global playbook” for defeating advertiser verification regulations, which the company knows would reduce scams. It includes making scam ads “not findable” for regulators searching Meta’s ad library through targeted scrubbing.

It's been a long time since I covered straight finance, but to see analysts -- and Bloomberg -- questioning the reliability of US inflation and labor data like this is remarkable.

Strange(r) times ahead, I guess.

To grow its ad biz in China, Meta has relied on ad agency partners given the power to create special enforcement-protected ad accounts and share them with resellers. The system produces so much fraud that Meta internally calls China its top “scam exporting nation.”

I’ve spent almost seven years covering Meta and have had a good deal of exposure to internal work product on teen well-being. But a Friday filing in the school district social media litigation breaks some ground on Meta’s causal findings regarding social media harm.

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.

Meta earns $3.5 billion every six months from showing Faceboon and Instagram users 15 billion “higher legal risk” scam ad impressions a day, internal documents state.

That haul vastly exceeds how much the company expects regulators
To fine it for running scam ads.

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.
October 24, 2025 at 4:42 PM
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.
