## Nightsky 40M Dataset

Use it as you wish! Very little preprocessing.

# Request data deletion

A user may request removal of their data by e-mailing nightsky-rm@proton.me with a subject line of "Delete My Data".\
As I don't collect usernames/DIDs, you must specify the position of every individual row you would like to be removed and include your Bsky account for verification.

Each request must only contain rows pertaining to a single account.\
Requests may take up to a week to be processed. Received requests are deleted immediately after being processed.
