Dupe: Gmod Server Crasher
Do not rely on the base game to protect itself. The Garry's Mod developer community has created vital security tools available on GitHub and the Workshop:
A server crasher dupe is a saved creation that contains a specific arrangement of props, entities, or data designed to overwhelm a server's processing capabilities. When a player selects this dupe from the Steam Workshop or their local files and spawns it, the server attempts to calculate the physics, constraints, or code embedded within the object.
Server owners pay monthly fees for hosting. Constant crashes ruin the return on investment and deter community donations.
These tools detect anomalous spawning patterns, impossible constraint counts, and known crasher dupe signatures. Most result in a “global ban” shared across hundreds of servers via community blacklists. GMod’s also use SteamID-based bans. gmod server crasher dupe

Configure your administration mod (like ULX or SAM) to forbid the duplication of high-resource entities like thrusters, dynamite, or custom scripted entities. Do not rely on the base game to protect itself
Understanding how these crashers work, why players use them, and how to defend your community is vital for any server administrator. How Server Crasher Dupes Work

Garry’s Mod (GMD) remains one of the most resilient sandbox games in PC history. Its longevity relies entirely on player freedom, custom scripts, and the Steam Workshop. However, this absolute freedom creates a massive security vulnerability: the server crasher dupe.
