DoomScroll analyzes the sentiment of posts and comments and allows you to filter them by different metrics. Ensure that your Reddit feed is more positive (or negative). Or only see posts above a certain upvote ratio threshold.

Overall, filtering by only positive posts will lead to more positive interactions, with more agreeable content. Fitlering by only negative posts will lead to more contoversial posts and comments, including more angry, edgy, or depressing content.
