" Roadmap and Growth

A few weeks ago, we intentionally slowed our invite roll-out while we built more moderation tooling and capacity for users on the app. We staffed a content moderation team with shifts that cover a 24/7 schedule, and consulted with trust and safety experts to establish new processes and policies to support a growing userbase. We’ve resumed sending out daily invites to the waitlist, which is where the majority of users already on Bluesky received their invites. For those who don’t know someone personally with an invite code, the waitlist is the fastest way to receive a code, though please be patient as we work through the list. "
