The Reddit blackout, explained: Why thousands of subreddits are protesting third-party app charges

Thousands of Reddit discussion forums have gone dark this week to protest a new policy that will charge some third-party apps to access data on the site, leading to worries about content moderation and accessibility.

“Reddit is killing third-party applications (and itself)," multiple subreddits wrote in posts seen on the platform's homepage this week.

The new fees are part of broader changes to Reddit's API, or application programming interface, that the company announced recently.

Organizers of the blackout, which began Monday, say Reddit's changes threaten to end key ways of historically customizing the platform — which relies heavily on the work of volunteer moderators. Subreddit “mods" often use tools outside of the official app to keep their forums free of spam and hateful content, for example, as well as improve accessibility.
