🚨 A recent @pnas.org article raised serious concerns about LLM-based manipulation of online surveys.

Good news: We’re not helpless. In a new #OpenAccess article with @jkhoehne.bsky.social #bwolf, we show that LLM-driven bots can be detected using simple prompt injections.

Increasingly, the Internet/social media feels like such a horrible place. And then a video like this pops up and gives me hope that not all is lost.

Brave New Data Access World: What the Digital Services Act (DSA) Means for Researcher Access to Digital Platforms

Hybrid event [A5, 6, Room A231 + Zoom]
Dezember 03, 2025, 13:45-15:15

Abstract
The European Union’s Digital Services Act (DSA) marks a turning point for the study of digital platforms by establishing a legal framework for researcher access to platform data, including from major social media companies. Article 40 of the DSA outlines how researchers can request such access, opening unprecedented possibilities for empirical investigations into the digital public sphere. Yet, the practical implementation of this right to data access raises important challenges. Questions of eligibility, the scope of accessible data, and the ethical and technical standards required for secure processing are central to understanding what this new regime will mean in practice. This talk provides an overview of the DSA’s data-access provisions, explains their relevance for the research community, and discusses what opportunities—and limitations—emerge for studying systemic risks, algorithmic effects, and platform governance. It reflects on early experiences with Article 40 implementation and considers what it will take to build a sustainable infrastructure for independent, policy-relevant research on digital platforms in Europe.

Presenter
Jakob Ohme leads the interdisciplinary "Digital News Dynamics" research group at the Weizenbaum Institute in Berlin, exploring the impact and dissemination of professional journalism on digital platforms versus other sources like influencers or AI. His work emphasizes the changes digital and mobile communications bring to news consumption and political engagement, particularly across different generations. Jakob Ohme is dedicated to advancing digital methodologies in political communication and journalism research, notably through the innovative use of digital trace data. He's also a Co-Principal Investigator in the #DSA40 Collaboratory, foc…

If you work with individual-level data from Very Large Online Platforms or Search Engines (VLOPSEs), then you probably want to read - and hopefully sign - this letter!

DSA40 Data Access Collaboratory @dsa40collaboratory.bsky.social · Nov 25

We've published an Open Letter urging EU policymakers to reject the Digital Omnibus' proposed Amendment to Article 12(5) GDPR, which would undermine citizens' data access rights & the researchers who depend on them for #DataDonation research.
Read & sign: shorturl.at/e1mr4 - your signature matters.

the background depicts the proposed amendment, the foreground reads "Open Letter: The Amendment to Article 12, paragraph 5 GDPR in the Omnibus Proposal Undermines Evidence-Based Policymaking"

Yes. Some of the cheap vendors are already struggling because they cannot compete with the new wave of even cheaper data (‘silicon samples’).

I really see a potential threat for studies that recruite samples via social media platforms (but these samples were wacky even before LLMs) or some river sampling. Not for well managed (nonprobability) online panels and certainly not for high-quality probability panels.

Florian Keusch @floriankeusch.bsky.social · Nov 18

But how would this work in reality? Say I build multiple bots, then I would need to register for each of that bot in a panel. If a panel follows the ESOMAR guidelines then they do double-opt-in verification and might even require a bank account or at least a unique email.

Florian Keusch @floriankeusch.bsky.social · Nov 18

But there are a number of high quality probability based online panels where I think the influence of LLMs and AI-respondents will be very limited. These are not cheap for a reason..

Florian Keusch @floriankeusch.bsky.social · Nov 18

True for nonprobability online access panels that allow self-selection and river sampling-like approaches. Many of them had major quality issues even before LLMs.
