How we check
We only call a server official with proof: Discord's Verified badge, or the invite published on the studio's own website, store page or official social account. Fan-run servers come from a subreddit, a wiki, a community site or a server directory. Cheat, gambling, account-selling and NSFW servers are left out. Subreddits are listed for convenience and never labelled official. The research was AI-assisted and every Official label was challenged by a second check. Member counts are a snapshot (October 12, 2026). More about how we check.
Run one of these servers and want it changed or removed? Email us and we'll sort it within a week. There's a small badge you can put on your own site if you like.
