Mojang vs Anarchy Servers: 2b2t’s New Rules, the 6b6t Blacklist and the AnarchyMod DMCA Explained

The short version: Mojang now enforces its usage rules on servers that market themselves as rule-free. 2b2t added rules in December 2025 after what it called an official notice from Mojang and Microsoft. 6b6t refused, and on July 15, 2026 Mojang added it to the game’s built-in server blocklist. 6b6t answered with AnarchyMod, a client mod that ignores the block. Mojang’s DMCA notice got the mod’s code pulled from GitHub on September 17. As of late October the server is still online, the mod is still distributed elsewhere, and GitHub hadn’t acted on 6b6t’s counter-notice.

• Jul 156b6t added to Mojang’s blocklist
• 4,318Entries on Mojang’s server blocklist (Sep 4, 2026)
• 1,155+Players 6b6t reported during its August event
• 40 daysWithout a GitHub reply to the counter-notice, by Oct 27

How does Mojang’s server blacklist work?

Minecraft Java checks every server address against a list Mojang publishes at sessionserver.mojang.com/blockedservers. The list holds SHA-1 hashes of blocked addresses, one per line, including wildcard entries for whole domains. If the address you type matches, the game won’t connect, and the server looks offline. It doesn’t take the server down. It just blocks the official client from reaching it. Bedrock has its own enforcement, and Xbox account rules apply to chat there, which is how players have been suspended for swearing even on privately run anarchy servers.

Timeline

• December 2025: 2b2t, the oldest anarchy server (running since 2010), adds rules against swearing, controversial builds, insulting admins and lag machines, citing pressure from Mojang and Microsoft. It is not blacklisted. The same month, 6b6t says another anarchy server, Purity Vanilla, was blocked.
• May 2026: creators document the crackdown as 2b2t removes offensive builds and longtime players say “true anarchy” is dying.
• June 2026: the owner of a Bedrock anarchy server says one of his players got an official Minecraft suspension for swearing on his own no-rules server.
• July 15, 2026: Mojang adds 6b6t’s addresses to the Java blocklist without warning. 6b6t releases AnarchyMod, a client-side Fabric mod, and reports 250+ players online within 48 hours.
• August 2026: TheMisterEpic’s video on the blacklist drives new interest, and 6b6t reports 1,155+ concurrent players during a dupe event. Rival 8b8t publicly admits its player numbers are falling and cuts side projects.
• September 3, 2026: 6b6t’s changelog reports that it has also been blocked on Bedrock.
• September 17, 2026: a Microsoft employee files a DMCA notice for Mojang AB, arguing the mod’s purpose is to bypass restrictions Mojang placed on 6b6t. GitHub disables the AnarchyMod repository and its forks, and the page now returns HTTP 451.
• September 18 to October 27, 2026: 6b6t files a counter-notice, moves downloads to its own servers and CurseForge, and follows up three times. By October 27 it says GitHub hasn’t sent a human reply in 40 days.

What is proven and what is disputed?

Why is Mojang doing this?

Mojang hasn’t explained individual decisions, but the direction is clear. Its usage guidelines and community standards apply to every server that uses its game and accounts, and regulators are pushing harder on child safety, from Australia’s eSafety notices to the US lawsuits. Anarchy servers that allow hate speech or extremist builds are the easiest target. Servers that add basic rules, like 2b2t, have so far stayed off the list.

The MOTD crackdown: blocked for a swear word

From mid-2026 the blacklist reached far beyond anarchy servers. Server owners reported that Mojang’s enforcement team was flagging servers over swear words or crude jokes in their MOTD, the line of text under a server’s name in the multiplayer list. That included small, whitelisted servers for friends that were never advertised.

• How servers are found: the status ping that returns your MOTD answers before the whitelist is checked, so any reachable server’s MOTD is readable.
• How it’s enforced: owners describe emails sent to ISPs and hosting providers with a 5-day deadline before the whole IP address goes on Mojang’s client-side blocklist. Mojang says it can’t block a single port, so shared hosting IPs can be hit by one customer’s MOTD.
• How to fix it: change the MOTD, then appeal through Mojang’s form. Recent reports say unblocking takes about a day.

You can check whether a domain is blocked against Mojang’s public list of hashed blocked servers, which community tools such as mc-api and MC Blacklist make readable.

What it means for players

• 2b2t is no longer rule-free. Swearing, offensive builds and lag machines can get you muted or banned. For the server’s history, see our 2b2t preservation story.
• 6b6t needs a client mod on Java. Installing mods that change how the game handles Mojang’s blocklist is your own risk. Only download from the project’s official channels, because fake “anarchy clients” are a common malware lure.
• Expect more of this. The blocklist now has thousands of entries, and Mojang has shown it will go after workarounds, not just servers.
