Privacy Policy for Bluesky Measurements

Who are you?

We are a team of researchers from multiple institutions. As a first point of contact, refer to the Communication Networks Lab at TU Darmstadt, Germany.

What data are you collecting?

As part of our ongoing research 12, we are collecting data of the Bluesky social network. We collect data of multiple components of the network:

  • A log of the public Bluesky Firehose
  • A mirror of the public plc.directory
  • The output of public Labelers
  • Snapshots of public content of the entire social network

Why are you doing this?

Our overarching goal is to derive general, non-personalized insights and statistics about Bluesky. We plan to make the results of our research public but will not make our raw collected data public at any point. Furthermore, we may release anonymized versions of some datasets, especially if we believe them to be useful to the wider community.

We use collected data for testing purposes during the development of new methods and their implementations.

We will use the collected data only for furthering the goals outlined above. We will use collected data only for purposes that are explicitly stated in this document and purposes that are permissible with respect to Art. 6 (4) GDPR.

We operate within the bounds of European data protection law, specifically Art. 5 (1) (e) GDPR.

For how long are you going to keep this data?

At the moment, we are operating as an indefinite research archive for the data outlined above. We believe it is vital for future researchers to collect and preserve these datasets. We are constantly reflecting on our data storage practices. If we conclude that some data fields or whole data sets are no longer needed for our intended purpose, we will delete them accordingly.

Who are you sharing this data with?

We are sharing parts of this this data, on request, with researchers working on thematically similar topics, only after we are convinced that our data helps them in their research and that the goals of their research overlap with our own purposes for collecting and storing the shared data. In each individual case, we determine the minimal subset of data that is necessary to hand out. We also inform the receiving researchers of the delicate nature of this data and ask them to handle it responsibly and in line with our own privacy policy.
