Researchers say hate speech and misinformation on Twitter are up; CEO Linda Yaccarino says that's “incorrect” and touts improvements, like ad placement controls
Coupled with $13 billion of debt, the company is in more than a shaky position. … Twitter: @twitterbusiness : To our partners, we want to address a recent Bloomberg article which claims that harmful content viewed on Twitter has gone up over the past six months.

Linda Yaccarino / @lindayacc : A Bloomberg article today claims that harmful content viewed on Twitter is on the rise, but that's not true.

Context & Ripple Effects
The fight over this Bloomberg article lands at the worst possible moment for Twitter's sales operation. Pathmatics tracking already showed about 70% of the platform's top 100 pre-takeover ad spenders had stopped spending by December, and an investor update put revenue down roughly 40% year over year as advertisers fled — many citing exactly the harmful-content rise the company now disputes.
Yaccarino's counterargument leans on Twitter's own metrics — 99.99% healthy impressions — plus ad placement controls pitched directly at partners. But the company has simultaneously restricted independent researchers' data access through new API pricing, so the outside studies that once audited its brand-safety claims have lost their raw material.
First-order effects
- Advertisers weighing a return must now choose between Twitter's self-reported health figures and third-party research they can no longer independently verify, since API pricing changes have cut researchers off from the data.
- For Yaccarino, whose remit includes sales under the newly announced split where [[a:842651|Musk takes product and engineering while she leads legal, sales, and trust-and-safety oversight]], publicly disputing the measurement is the core of her job: the pitch to partners is that placement controls, not content trends, define what brands see.
Second-order effects
- With independent audits constrained, brand-safety verification shifts to vendors and advertisers' own tools — firms like the Pathmatics-measured spenders Mars and Jeep can benchmark impressions themselves rather than accept Twitter's 99.99% figure.
- Every week the dispute stays unresolved extends the advertiser drought documented since late 2022, compounding the pressure of the company's roughly $13 billion debt load on cash flow.
Third-order effects
- If platforms restrict researcher API access while disputing outside measurements, brand safety becomes a matter of platform self-attestation — a structural shift that pushes regulators and major buyers toward demanding standardized, third-party-audited transparency as a condition of spending.
- The pattern points toward social platforms splitting into a sales-led trust function and a product-led owner, with the credibility gap between internal metrics and external research becoming the decisive variable in advertising recovery.
The trend: Platform trust is moving from independently verifiable measurement toward self-reported metrics, forcing advertisers and regulators to decide whether internal dashboards can substitute for open researcher access.
