Huge Collection of Reddit Votes

Data on over 44 million upvotes and downvotes cast between 2007 – 2020.

This is a tab-delimited list of votes cast by reddit users who have opted-in to make their voting history public. Each row contains the submission id for the thread being voted on, the subreddit the submission was located in, the epoch timestamp associated with the vote, the voter’s username, and whether it was an upvote or a downvote. There’s a separate file containing information about the submissions that were voted on.
