the Reddit community is still reckoning with the consequences of the platform's API price hike. The changes have led to the shuttering of numerous third-party Reddit apps and have pushed several important communities, like the Ask Me Anything (AMAs) organizers, to reduce or end their presence on the site.

The latest group to announce its departure is BotDefense. BotDefense, which helps removes rogue submission and comment bots from Reddit and which is maintained by volunteer moderators, is said to help moderate 3,650 subreddits. BotDefense's creator told Ars Technica that the team is now quitting over Reddit's "antagonistic actions" toward moderators and developers, with concerning implications for spam moderation on some large subreddits like r/space.

BotDefense started in 2019 as a volunteer project and has been run by volunteer mods, known as "dequeued" and "abrownn" on Reddit. Since then, it claims to have populated its ban list with 144,926 accounts, and it helps moderate subreddits with huge followings, like r/gaming (37.4 million members), /r/aww (34.2 million), r/music (32.4 million), r/Jokes (26.2 million), r/space (23.5 million), and /r/LifeProTips (22.2 million). Dequeued told Ars that other large subreddits BotDefense helps moderates include /r/food, /r/EarthPorn, /r/DIY, and /r/mildlyinteresting.

On Wednesday, dequeued announced that BotDefense is ceasing operations. BotDefense has already stopped accepting bot account submissions and will disable future action on bots. BotDefense "will continue to review appeals and process unbans for a minimum of 90 days or until Reddit breaks the code running BotDefense," the announcement said. The announcement also advised "keeping BotDefense as a moderator through October 3rd so any future unbans can be processed."
