Server owners often have to disable entire tools to prevent this.

Add these lines to your server.cfg file to restrict explosive physics calculations:

The community has developed highly effective, free tools specifically designed to detect and block malicious net messages and overloaded dupes. You should install these immediately:

: Frequent crashes ruin the experience for regular players and can lead to data loss or corruption of server databases.

You do not need to buy expensive, proprietary scripts from secondary marketplaces to protect your server. The global open-source community provides excellent, actively maintained protection tools for free. 1. FPP (Falco's Prop Protection)
