Miss the old minecraft before Microsoft? Alfheim.pw is a completely unmoderated 1.7.2 vanilla mature minecraft server. The server typically has between 3-15 players online and is a small niche community to hang out and chat in.
You can do, build, or say anything you want.
There are no staff, and trust other players with a grain of salt.
No money is made from the server, there are no ranks, no purchasable items, and the server has 16 terabytes of storage at the players disposal and long-term hosting.
If the server crashes it will turn itself back on.
