Death-Ban is when a player dies/or is killed the player will be banned from the server.
When a player is killed by the environment (PvE) another player (PvP) or any other means (Suicide) he/she is banned from joining the server for the amount of time specified. In this case it would be for 3 days (72 hours). The player cannot join the server until this time has expired.
NOTE: If a player dies on HCFactions, they're only banned from HCFactions. Not the entire Shotbow Network.
