This plugin automatically bans ALT accounts of users previously banned for a length of time defined in the config and with a custom message which can also be changed in the config.
It does this by temporarily storing the IP address of a banned user and banning all players which join with the same IP address for an amount of time defined in the config. After this time has surpassed the IP will be allowed access to the server again and any ALTs will remain banned.
Installation
This plugin can be installed on either Bungee or Spigot. Just drop it in the plugins folder with AdvancedBans and you're good to go.
Set up
This plugin needs no additional setup and will work right out the box. There is a config file with a few changes here:
# The user which bans the players
# MAX 16 CHARACTERS!
ban_user: "Auto Ban"
# The duration a player should be banned for (-1 = Permanent)
ban_duration: -1
# The amount of seconds the plugin should check for ALT accounts under the same IP
# default: 600
ban_period: 600
# The message which should be received for an ALT joining under the same IP as a previously
# banned account
# default: "Evading punishment of an alt (%banned_player%)"
ban_message: "Evading punishment of an alt (%banned_player%)"
Commands Everything else is automatic with /ban. But you can use /autoban to reload the config
Permissions If a user can /ban on your server then this plugin will automatically hook into it.
autoban.admin - Reload Config
autoban.bypass - Prevent being banned
Disclaimer
This plugin is extremely early beta, so feedback and bug reports are appreciated!
This plugin is only so reliable. It will cause issues if multiple players are on the same IP such as siblings playing on the server as 2 different accounts. There isn't an easy way to solve this but I am looking into other ways.
