How to Remove players scores?

To wipe their data, first, you need to ofc ban them, use this:

local bans = {"edg90210", "gabo253464", "SF_REACHER", "Casilini"}
game.Players.PlayerAdded:Connect(function(p)
    for _, v in ipairs(bans) do
          if p.Name == v then
               p:Kick("wooh funny exploit man xddd")
          end
     end)
end)

It searches through the table of banned players, then if they're in it it kicks them Then you'll need to actually wipe their data:

local dss = game:GetService("DataStoreService")
local ds = dss:GetDataStore("DATA_STORE_NAME_HERE")
local bans = {"edg90210", "gabo253464", "SF_REACHER"}
game.Players.PlayerAdded:Connect(function(p)
    for _, v in ipairs(bans) do
          if p.Name == v then
               p:Kick("wooh funny exploit man xddd")
               ds:SetAsync(p.UserId, 0)
          end
     end)
end)

This then further resets their datastore.
