Dataset of user and tweet ids of followers of news media accounts

## Data

All files are [xz compressed archives](https://en.wikipedia.org/wiki/XZ_Utils) and
can be unpacked with, e.g., `unxz user_ids.dat.xz`. Each file contains one id per
line, which are in some cases sorted ascendingly to improve compressibility.

The ids of `tweet_ids.dat.xz` and `retweet_ids.dat.xz` correspond to tweet_ids of Twitter,
but for convenience we split categorized them into retweets and regular tweets.

For each news outlet Twitter account we provide a file with all follower ids which
followed them at one point in the end of March 2021. These are suffled and the tweets
provided in the files above originate from the first few percent.
