Let’s be real. You’ve spent 400 hours building your castle. You’ve balanced the swords, tweaked the gravity, and coded a trading system that actually works.
Do not trust the client. If your client script sends data to a RemoteEvent , ensure the server validates that data before acting on it. 4. Monitor Server Performance

Some exploits rely on sending massive amounts of text data through the chat system to freeze other clients. Anti-crash measures can include forking the default chat system to include custom message validators .
If you are running complex math calculations that could potentially stall the server, wrap them in a task.spawn() or task.defer() block. This ensures that even if that specific calculation hangs, it runs on a separate thread and does not freeze the core gameplay loop. Step 3: Server-Side Instance Limits (Anti-Lag Machines) Let’s be real
-- Workspace safety loop to prevent massive physics-based server stalls task.spawn(function() while true do task.wait(5) -- Run sanity checks periodically for _, player in ipairs(Players:GetPlayers()) do local character = player.Character if character and character:FindFirstChild("HumanoidRootPart") then local hrp = character.HumanoidRootPart :: BasePart -- Check for NaN (Not a Number) or infinite velocity exploits local velocity = hrp.AssemblyLinearVelocity if velocity.X ~= velocity.X or math.abs(velocity.X) > 5000 or math.abs(velocity.Y) > 5000 then hrp.AssemblyLinearVelocity = Vector3.zero player:Kick("Physics manipulation detected.") end end end end end) Use code with caution. How to Test Your Anti-Crash System
If a RemoteEvent takes arguments, check them on the server before executing them. For example: Do not trust the client
A proper anti-crash script will listen to these events and say: "Wait, this player just tried to spawn 500 items in 0.1 seconds. That's impossible for a normal human." 3. Implementation: The Watcher Script

-- Local Script Stress Test local event = game:GetService("ReplicatedStorage"):WaitForChild("CustomGameplayEvent") for i = 1, 1000 do event:FireServer("SpamData") task.wait() -- Fires rapidly end Use code with caution.
