ChatCop

Added:

• Private messages and other chat commands (/msg, /me, /mail and more) now go through the same filters as normal chat
• Muted players can no longer talk through private messages or other chat commands
• Sign, book and anvil rename filtering
• Chat slowmode, a global chat lock, and a first-join chat delay that stops bot raids
• Raid detection for the same message arriving from many accounts at once
• Mutes and unmutes now work on offline players
• Violation points, warnings and history are now kept across restarts
• Per-filter bypass permissions, so you can exempt someone from one filter instead of all of them
• Mute-exempt and mute-override permissions so staff cannot mute each other by accident
• New subcommands: check, clear, mutelist, slowmode, lock and unlock
• Tab completion on every command
• Built-in update checker that tells you when a new version is out
• Optional bStats metrics
• Discord alerts for manual mutes, unmutes and warnings
• The mute reason is now shown to the muted player
• Sexual content is now detected and reported separately from slurs
• Automatic log file rotation

Fixed:

• Words hidden with symbols no longer pass straight through the filter
• Letter-spaced words are now caught
• Words with trailing punctuation could slip past detection
• Staff alert sounds threw a console error on 1.21.3 and newer, and no sound played at all
• Players with the bypass permission could talk while muted
• Muted players could talk freely in any world where filtering was disabled
• Messages could be delivered uncensored while the player was told they had been censored
• Shadow-flagged messages could still be relayed to Discord by chat bridge plugins
• Ordinary chat was flagged as advertising, such as "that was fun.me and you" or "see you.tv"
• Custom blocked domains were still enforced after URL blocking was turned off
• A whitelisted word could be used to smuggle a blocked word past the filter beside it
• The word "crackers" was flagged as a slur
• A blank entry in a blocked phrase list silently blocked every message on the server
• A custom phrase like "nega" also matched "negative"; plain words now match as whole words only
• Reloading could throw an error if someone was chatting at that moment
• Certain censor characters threw an error and dropped the message
• All active mutes were silently wiped on reload when mute saving was turned off
• Ampersands in messages were mangled, turning "Fish & Chips" into broken text
• The flood window was capped at 10 seconds no matter what you configured
• Duplicate message detection compared messages inconsistently and under-detected repeats
• A single profane word could count as two or three against the per-message limit
• The configurable no-permission message was never actually shown to players
• The statistics permission was documented but never checked
• Testing a message polluted the tester's own spam tracking and could trip their own filter
• An @everyone inside a flagged message pinged the entire Discord server
• Mute settings were being read but were missing from the config file entirely
• A mute duration without a unit silently became a permanent mute

Improved:

• Now runs on Java 17, restoring support for 1.20.x servers that run Java 17
• PlaceholderAPI support expanded to 15 placeholders
• Discord alerts are queued and rate-limit aware instead of one request per message
• The violation log is buffered and rotated instead of being rewritten on every message
• Settings are cached instead of being re-read for every single message
• Advertising detection now sees through spelled-out addresses like "example (dot) com"
• History and message testing now work for offline players and from the console
• Unmute tab completion suggests players who are actually muted
• Staff alerts can be mirrored to console, and the quoted message length is configurable
• Config file rewritten with clearer comments and no leftover example values
• Existing config files keep working after updating, since every new option has a default
• Full documentation refresh
