What is CoreSpectrum?
CoreSpectrum is a moderation and behavior control plugin designed for Survival, RPG, Semi-RPG, and Survival servers with minigames. It combines a complete reputation system (0 to 1000) with a fully featured automatic and custom jail system, everything configurable and with total persistence.
The plugin does not only punish — it also rewards good behavior and gives server staff real, visible control over problematic players without relying on external jail plugins or constant manual moderation.
What does it do?
Reputation System
- Range from 0 to 1000 (default starting value: 500)
- Below 500 = Negative Reputation | Above 500 = Positive Reputation
- Automatic +1 reputation every 3 minutes if the player has no incidents
- Reputation loss when hitting players (configurable per tool):
- Hand: -1
- Shovel: -2
- Pickaxe: -3
- Sword: -4
- Mace: -10
- Killing a player: -300 reputation (configurable)
- Shared IP logic: if a new player joins with the same IP as someone who has negative reputation, they start with reduced reputation (configurable)
- 7 reputation levels with progressive effects (Glow, damage reflection, speed reduction, pearl/chorus/TPA blocking, chat cooldowns, accelerated hunger, particles, etc.)
- Special extreme effects (Mining Fatigue, Blindness and Poison) at very low reputation
- Whitelist of players who never receive negative effects and cannot be jailed
- Automatic jail: if a player with ≤100 reputation kills another player, they are automatically sent to jail (with time scaling: 10 → 20 → 30 minutes)
- WorldEdit-style selection system using a special stick
- Creation of multiple jails with defined regions
- Configurable spawn point per jail
- Temporary or permanent jail
- Jailed players cannot leave by walking, ender pearls, chorus fruit, or teleport commands
- Custom scoreboard visible only to the jailed player (shows remaining time or “Permanently Imprisoned”)
- PvP toggle per jail
- Full persistence (survives server restarts)
Because most servers share the same problems:
- Toxic players who constantly kill, push, or harass others
- Alternative accounts (alts) created to continue griefing
- Moderators who cannot be online 24/7
- Generic jail plugins that do not integrate with player behavior
- Incomplete reputation systems that lack real consequences
