Removed old kick/ban system for griefing and hacks. Cheating detection redone to stop inventory editors going above the normal limits. Revamped KillTile abuse detection to be always on. Removed old hacks/exploit detection for exploits fixed by Redigit properly. Removed some permissions and added one for killtile abuse detection. Removed old configurations that are not used anymore. AntiHack/Protection System COMPLETELY revamped to properly block and revert all actions that are abusive. Item Ban List is now the primary method to control various griefing items. To block Explosives or Sandguns or other items, use the Item Ban List. Banned items are able to exist in your inventory but the server will ignore all attempts to use those items. To protect against hack clients doing world edit type actions, use regions and spawn protection.
