A small summary about the minecraft server we have setup:
Server IP: 176.31.102.129:25575
Version: 1.11
PVP: Enabled except for predefined areas such as the spawnarea (This may change or not)
Maxplayers: 30 (can be modified if needed)
Spawnarea is widely secured denying breaking and placing blocks aswell as pvp
Any kind of mods that give an unfair advantage such as xray( either as resource or plugin) or minimap with player locations are strictly forbidden and will lead to a permanent ban.
There is no need to randomly attack people just because PVP is enabled.
