Blacklist

Blacklist

by Sambo

Your private note list about players — local only, and only for you.

You played a round with someone who threw everything off the ship. Two weeks later the same guy

joins again, using a different name, and you don't recognise him. That's what this mod is for:

you leave yourself a note, and next time your chat tells you.

⚠️ First things first: this is not a shared naming-and-shaming list

With a mod called "Blacklist" that's the obvious question, so here it is right at the top:

| | |

|---|---|

| Sends data to a server? | No. There is no server. |

| Downloads lists from anywhere? | No. |

| Shares your entries with other players? | No. |

| Custom RPCs / network packets? | No. No Netcode Patcher required. |

| Telemetry, analytics, crash reports? | No. |

| Do other players need the mod? | No. They can't even tell you're using it. |

The mod is entirely client-side. Your list is a text file on your own disk. The chat output is

visible to you alone — it goes through HUDManager.AddChatMessage, the same method the game

uses to show you local system messages. It transmits nothing.

So this isn't a community ranking or a reputation system. It's a personal note-taking tool for

people you'd rather not play with again — like a sticky note next to your monitor, except it taps

you on the shoulder by itself.

What it does

As soon as you join a lobby and the Steam IDs have synced, the mod checks every player against

your list and reports hits in your local chat:!! BLACKLIST!! NewName - GRF,STL

(previously known as: Kevin)

GRF = griefer, STL = loot thief

"threw everything off the ship on Titan"

The key is always the SteamID64, never the name. Names are freely changeable in Lethal

Company — someone who renames themselves is still recognised, and the old spelling is shown

alongside.

Chat commands

Open the chat and type. Anything starting with /bl is intercepted locally and never sent to

the lobby.

| Command | Effect |

|---|---|

| /bl who | check every player in the lobby, with Steam IDs |

| /bl add [note] | create or extend an entry |

| /bl rm | delete an entry |

| /bl seen [name] | recently seen players, with Steam IDs |

| /bl list | current entries |

| /bl codes | code legend |

| /bl reload | re-read the files from disk |

| /bl help | help |

Example:

/bl add Kevin GRF,STL threw everything off the ship on Titan

The name doesn't have to be complete — an unambiguous substring is enough. If it is ambiguous,

the mod asks instead of guessing. Purely numeric input is treated as a SteamID64.

Names are resolved in this order: current lobby → existing entries → name cache. The cache is

why you can still add someone after they've left the lobby.

Codes

Three severity levels, colour-coded in chat.

🔴 Bad — GRF griefer · STL loot thief · SAB sabotage · TK teamkill · TOX toxic · SLR slurs · CHT cheats

🟠 Warn — EARLY starts too early · LEAVE leaves people behind · RQ rage-quit · AFK · MIC mic spam · TRL trolling · LAG · NOOB

🔵 Info — NL only if agreed beforehand · MOD needs mod sync · OK note only

You can invent your own codes — they work immediately, with no changes to the mod, and count

as Warn. An entry's level is always the highest of its codes.

The files

Both live in BepInEx/config/Blacklist/ and can be edited with any text editor. No JSON, no

Newtonsoft dependency.

blacklist.txt — your entries. Comment lines starting with # survive saving.

SteamID64 | CODES | last known name | note

76561198000000000 | GRF,STL | ExampleName | threw everything off the ship on Titan

known_players.txt — an automatic name cache for every player you've seen, not just the

listed ones. Capped at the 500 most recently seen.

SteamID64 | last known name | last seen (UTC)

76561198000000000 | ExampleName | 2026-07-24 21:03

If you edit by hand, /bl reload re-reads both files without restarting the game.
