On last day of #aoir2025 @lionw.bsky.social presents our @weizenbauminstitut.bsky.social work on TikTok data donation from the 2025 German Federal Election - only 5% of content was political and the Left party could capitalize most in reaching voters of other parties with their content on TT.

This was a great roundtable, lots of important questions from the audience, giving the impression that data donations will be around for longer, if we get it right (based on comments from the audience on postcards) #aoir2025

How often is too often in ESM research?
🚨New study out!
We compared 6 beeps/day vs. 12 beeps in 2 h bursts.
Both work, but burst designs show more fatigue + attrition — still useful if high temporal precision matters.
App onboarding, though? Big bias alert. 📱

Our new policy paper on #DSA40 explains the detailed processes of data access (with updates from Delegated Act), describes still existing bottlenecks, and discusses the challenges of legal right vs. platform resistance and is asking all stakeholders to act in good faith and to deliver.
