Reddit publishes its 2021 transparency report: 297M pieces of content were removed out of 5.8B total, 2,813 users and 2,625 subreddits were permanently banned

Context & Ripple Effects
Reddit's 2021 transparency report lands a year after its 2020 edition, which logged 233M content removals out of 3.4B submissions — so the new figures show both enforcement volume and overall posting activity growing together. The report also arrives mid-arc in Reddit's enforcement escalation: the platform had already banned nearly 7,000 subreddits in mid-2020 over hateful content.
The transparency-report format itself has a contested history at Reddit — the company quietly deleted its surveillance 'warrant canary' back in 2016 — which makes these annual disclosures one of the few remaining public windows into how enforcement decisions are actually made.
First-order effects
- Content removals rose to 297M out of 5.8B total posts (up from 233M out of 3.4B in the prior-year report), meaning Reddit's enforcement machinery scaled faster than raw submission growth — direct workload for its trust-and-safety operation and volunteer moderator base.
- The 2,813 user and 2,625 subreddit permanent bans set the baseline that Reddit's next report will be measured against, including its disclosure of a sharp 2022 jump in actions against non-consensual intimate imagery.
Second-order effects
- Legal-process pressure is compounding the moderation load: Reddit's DMCA takedowns surged from 4,352 in 2017 to 665,898 in 2021 while the share of denied requests fell from over 80% to roughly 27%, shifting the cost center from community moderation toward rights-holder response.
Third-order effects
- If the removal curve keeps steepening, manual and volunteer review gives way to automation — a path Reddit itself confirmed when it later reported AI systems catching 25K spammy posts per day — making the transparency report the primary check on algorithmic enforcement.
The trend: Platform transparency reports are hardening into an annual accountability benchmark, even as the enforcement they document scales from human moderation toward automated systems.
