Roblox Security: Anti-Exploit & Server-Side Validation
Core Principle
Never trust the client. Every LocalScript runs on the player's machine and can be modified. All authoritative logic — damage, currency, stats, position changes — must live on the server.
FilteringEnabled is always on in modern Roblox. Client-side changes do not replicate to the server or other clients unless the server explicitly applies them.
