--//  Variables

--  DataStore

local DS = game:GetService("DataStoreService")
local BanDataStore = DS:GetDataStore("BanDataStoreStudioTest")

--  Other Variables

local RStorage = game.ReplicatedStorage
local BanFunction = RStorage.BanPlayer
local UnBanFunction = RStorage.UnBanPlayer
local AdminIds = {261477936, 1, 156, -1}
local Storage = game.ServerStorage
local BanFolder = Storage.BanFolder

--//  Kick If Ban Date Not Met

game.Players.PlayerAdded:Connect(function(Player)

    --  BanLocals

    wait(.1)
    local PlayerBanFolder = BanFolder[Player.UserId]
    local BanDate = BanDataStore:GetAsync(Player.UserId)
    local DayLength = PlayerBanFolder.DayLength
    local Reason = PlayerBanFolder.Reason
    if BanDate then
        local Seconds = os.time()-tonumber(BanDate.BanLength)
        local Minutes = Seconds/60
        local Hours = Minutes/60
        local Days = Hours/24
        if Days <= DayLength.Value then
            Player:Kick(Reason.Value.." Please Appeal In Our Discord Server In Channel 'assassination-secrecy-appeal' For A Chance To Be Un-Banned Early Or Reduce!")
        elseif Days >= DayLength.Value then
            PlayerBanFolder.Reason.Value = ""
            PlayerBanFolder.DayLength.Value = 0
        end
    end
