Serversided anti cheat does not function for some reason?

I have an anti cheat where it catches a player tping, flying, FE, etc. etc. however it seems like it does not work. The script is not disabled and if I put in "print("test") it for some reason works. This script is inside ServerScriptService since local scripts can be bypassed so easy

local Players = game:GetService("Players")
game.Players.PlayerAdded:connect(function(player)
    print("test")
    local Character = player.Character
    local Backpack = player:WaitForChild("Backpack")
    local HumanoidRootPart = player:WaitForChild("HumanoidRootPart")
    local Bodys = {
        ["BodyGyro"] = true,
        ["BodyVelocity"] = true,
        ["BodyPosition"] = true
    }


    local function Kick()
        player:Kick("Caught by AntiGamingChair")
    end
    -->>:Anti TP
    local function CheckTeleport()
        if HumanoidRootPart == nil then
            return Kick()
        end

        local PositionFirst = HumanoidRootPart.Position

        delay(1, function()
            local PositionSecond = HumanoidRootPart.Position

            if (PositionSecond - PositionFirst).magnitude >= 130 then
                return Kick()
            end
        end)
    end

    -->>:Anti BTools
    Backpack.ChildAdded:connect(function(Obj)
        if Obj:IsA("HopperBin") then
            return Kick()
        end
    end)

    -->>: Anti fly
    HumanoidRootPart.ChildAdded:connect(function(Obj)
        if Bodys[Obj.ClassName] then
            return Kick()
        end
    end)

    -->>: Anti godmode
    Character.ChildRemoved:connect(function(Obj)
        if Obj:IsA("Humanoid") then
            return Kick()
        end
    end)

    while wait() do
        CheckTeleport()
    end
end)
