I did this and it seems not to be working.
The command is not being blocked, am not sure what am doing wrong

{
  "Enable logging": true,
  "Chat steamID icon": 0,
  "Сommand color": "#ffffff",
  "Remaining blocking time color": "#FFA500",
  "Blocked commands (command: seconds)": [
    {
      "Command": "Blocked for 1 day",
      "BlockDuration": 86400.0
    },
    {
      "Command": "Blocked permanently",
      "clan": -1.0,
      "clanhelp": -1.0
    },
    {
      "Command": "Not blocked",
      "BlockDuration": 0.0
    }
  ]
}
