is a core security feature in Roblox that ensures all important game logic — such as player position, health changes, and moderation actions — is handled on the server rather than on individual players' computers. This prevents exploiters from manipulating the game by sending fake information to the server.

-- Function to ban player local function banPlayer(playerName) -- Implement your ban logic here. This could involve adding the player to a database of banned players. local player = Players:FindFirstChild(playerName) if player then -- Simple example, you should replace with actual ban mechanism. warn(playerName .. " has been banned.") player:Kick("You have been banned.") end end

if not isAdmin then return end

Do you need help designing a for the panel?

This sits inside the GUI button. It detects the click and sends the player's name to the server.

This script processes the request. It includes a security check (User ID whitelist) to ensure exploiters cannot trigger the event. It also utilizes Roblox's native BanAsync API for persistent banning.

Ensure that the RemoteEvent used for banning can only be fired by legitimate administrators to prevent unauthorized users from hijacking your GUI to ban innocent players.

Place this inside the KickButton :

-- Script inside ServerScriptService local ReplicatedStorage = game:GetService("ReplicatedStorage") local Players = game:GetService("Players") local DataStoreService = game:GetService("DataStoreService") local BanDataStore = DataStoreService:GetDataStore("PermanentBanList_v1") local NetworkEvents = ReplicatedStorage:WaitForChild("NetworkEvents") local KickRequest = NetworkEvents:WaitForChild("KickRequest") local BanRequest = NetworkEvents:WaitForChild("BanRequest") -- CRITICAL: List the UserIds of players allowed to use this GUI local AdminIds = [12345678] = true, -- Replace with your Roblox UserID [87654321] = true, -- Replace with an admin friend's UserID -- Helper function to check admin status local function isAdmin(player) return AdminIds[player.UserId] == true end -- Helper function to find a player by partial name local function findPlayerByName(name) for _, player in ipairs(Players:GetPlayers()) do if string.lower(player.Name):sub(1, #name) == string.lower(name) then return player end end return nil end -- Handle Kick Requests KickRequest.OnServerEvent:Connect(function(playerSending, targetName, reason) -- Security Check: Is the sender an actual admin? if not isAdmin(playerSending) then warn(playerSending.Name .. " attempted to exploit the Kick RemoteEvent!") return end local targetPlayer = findPlayerByName(targetName) if targetPlayer then if reason == "" then reason = "No reason provided by administrator." end targetPlayer:Kick("\n[Kicked]\nReason: " .. reason) end end) -- Handle Ban Requests BanRequest.OnServerEvent:Connect(function(playerSending, targetName, reason) -- Security Check: Is the sender an actual admin? if not isAdmin(playerSending) then warn(playerSending.Name .. " attempted to exploit the Ban RemoteEvent!") return end local targetPlayer = findPlayerByName(targetName) if reason == "" then reason = "No reason provided by administrator." end if targetPlayer then -- Ban active player local success, err = pcall(function() BanDataStore:SetAsync("banned_" .. targetPlayer.UserId, Banned = true, Reason = reason) end) if success then targetPlayer:Kick("\n[Banned]\nReason: " .. reason) else warn("Failed to save ban data: " .. tostring(err)) end else -- Optional: Look up user ID if player is offline (requires extra API configuration) warn("Target player must be online to be banned via this simple script.") end end) -- Check if joining players are banned Players.PlayerAdded:Connect(function(player) local banData local success, err = pcall(function() banData = BanDataStore:GetAsync("banned_" .. player.UserId) end) if success and banData and banData.Banned then player:Kick("\n[You are Banned]\nReason: " .. (banData.Reason or "No reason specified.")) end end) Use code with caution. Best Practices for Moderation Scripts

Creating or distributing scripts that forcibly kick or ban other players from Roblox experiences (especially using "FE" – FilteringEnabled) is a violation of Roblox's Terms of Service. Such scripts are considered exploits (hacks). Using them can lead to a permanent account ban .

Consider linking your server script to a Discord Webhook using HttpService . Logging every kick and ban action keeps a permanent trail of your moderation team's activity outside of Roblox.

But sometimes, late at night, old-timers swear they hear a faint echo in the server’s dead zones—a whisper, begging for a kick that will never come.
