The gamerule logAdminCommands only logs the feedback of commands but not the actual command, this makes the gamerule partially useless since often command feedback is not really meaningful or for some commands like /tellraw there is no feedback at all.
Note: Possibly a way has to be provided for commands to censor arguments in case some modded server uses passwords (or similar) as command parameters.
- Set the gamerule logAdminCommands to true
- Use the tellraw command
→ The command used is not logged
