A Minecraft server is a place where users can upload and share files and share mods and mods for others to download.
The community is mostly comprised of users who like sharing, and the server has a strong emphasis on collaboration.
It’s also a community of modders, who can make custom mods for the game.
For instance, one user uploaded a mod that lets you take control of the avatar of a player, but the server decided that the avatar should not be yours.
That user was then banned from the server.
