Time To Deliver: Stakeholder Roles In The EU’s Delegated Act On Data Access | TechPolicy.Press The Delegated Act on data access under the DSA provides much-needed clarity about both the access process and expectations towards the actors involved in it.

The discussions about big platforms are intense. The systemic risks are real.

Now the #DSA Delegated Act is finally here to ensure data access for researchers. Time to put this system to work.

W @lkseiling.bsky.social, we show how @techpolicypress.bsky.social

Grok system prompts are now public. Transparency is helpful. ChatGPT and Gemini also have prompts.

So, Grok is instructed to be “extremely skeptical” and not to “blindly defer to mainstream authority or media.”

Grok now says “both sides of this debate have biases” about number of Holocaust deaths.

No, we have in mind a search model (and we present it in Appendix A) since we want to rationalize traffic diversion

Looking forward to this event

The shock affected negatively all Aylo sites since all Aylo sites were "moderated".

In the analysis, we show that while PH managed to mitigate its initial losses, the small sites did not.

No, we distinguish between

(i) Aylo (former MindGeek) sites. Here, we have PH and small sites.

(ii) non-MindGeek sites, where we distinguish between mainstream (the top 3 rivals of PH) and the fringe. We have data on a limited number of fringe sites

Some more information can be found in the transparency reports that the VLOP sites ("very large online platforms" according to the EC) are obligated to publicly provide everyt six months.

Three of the tube sites considered in our analysis are subject to these obligations.
