Incredibly useful tool on servers
Reputation ranks
Ranks only ever go up; points can drop but your rank stays.
About reputation ranksThis mod is a godsend for server owners, when new players join modded worlds they are often placed into a desolate spawn, ransacked 5k blocks in every direction. This mod does a good amount of work to fix that.
The fact this mod supports different types of storage such as chests and barrels and in a lot of cases successfully automatically detects when it needs to replace the loot blocks in structures meaning it can often work without any configs. Although in the few times it hasn't worked automatically it can be a giant pain to get working...
This mod makes me wonder whether something similar for valuable blocks in structures would be possible, though that'd be much harder to implement.
If you ever play modded adventure servers, use this.
