factorio.com bans is a switch on the Startup page. When it is on, your server checks each joining player against bans that Wube, the maker of Factorio, has put on factorio.com. It also tells factorio.com about the bans and unbans you make on your own server. It is off on a new server, and a change applies at the next start.
What it does
The game’s own manual describes it as: “Verify that connecting players are not banned from multiplayer and inform Factorio.com about ban/unban commands.”
That means two things:
- Players banned by Wube cannot join your server. You do not have to ban them yourself.
- Your bans are reported. When you ban or unban a player, the game tells factorio.com.
Your own ban list still works the same, with the switch on or off. See kick and ban players.
Turn it on
- Open the Startup page.
- Find factorio.com bans. Its text says “1 refuses players banned from Factorio’s multiplayer by Wube, and tells factorio.com about this server’s bans.”
- Set the value to
1. - Save the change.
- Restart the server. The change is read when the server starts, not before.
To turn it off, set the value back to 0, save, and restart.
Why it needs a restart
The panel passes this option to the game on its start line. The game does not read it again while running. Until the restart, the server behaves as before.
By hand
On a server you run yourself, the game option is --use-authserver-bans, added to the command that starts the server. The panel adds it for you when factorio.com bans is 1. Use it together with players who sign in with factorio.com accounts.
Players need a factorio.com account anyway
A new server only lets in players who sign in with a factorio.com account. That is how bans can follow a name. See only factorio.com accounts.
If it does not work
- The panel refuses the value. The field takes only
1or0. - A banned player still joins. Check that you restarted after the change, and that the server really started again (watch the Console tab).
- A player you want in is refused. Wube may have banned them. Turn the switch off and restart if you want your own list to be the only one.
