[…] In 2024, Bluesky grew from 2.89M users to 25.94M users. In addition to users hosted on Bluesky’s infrastructure, there are over 4,000 users running their own infrastructure (Personal Data Servers), self-hosting their content, posts, and data.
To meet the demands caused by user growth, we’ve increased our moderation team to roughly 100 moderators and continue to hire more staff. Some moderators specialize in particular policy areas, such as dedicated agents for child safety.

In 2024, users submitted 6.48M reports to Bluesky’s moderation service. That’s a 17x increase from the previous year — in 2023, users submitted 358K reports total. The volume of user reports increased with user growth and was non-linear, as the graph of report volume below shows:
Report volume in 2024In late August, there was a large increase in user growth for Bluesky from Brazil, and we saw spikes of up to 50k reports per day. Prior to this, our moderation team handled most reports within 40 minutes. For the first time in 2024, we now had a backlog in moderation reports. To address this, we increased the size of our Portuguese-language moderation team, added constant moderation sweeps and automated tooling for high-risk areas such as child safety, and hired moderators through an external contracting vendor for the first time.
We already had automated spam detection in place, and after this wave of growth in Brazil, we began investing in automating more categories of reports so that our moderation team would be able to review suspicious or problematic content rapidly. In December, we were able to review our first wave of automated reports for content categories like impersonation. This dropped processing time for high-certainty accounts to within seconds of receiving a report, though it also caused some false positives. We’re now exploring the expansion of this tooling to other policy areas. Even while instituting automation tooling to reduce our response time, human moderators are still kept in the loop — all appeals and false positives are reviewed by human moderators.
