Anti-Speed Hacker Script Not Working?

Asked by

I made this script to stop exploiters but it doesn't work. Can anyone help me? There's no output. It's supposed to check every 20 seconds to prevent lag is someone is exploiting. Also its in a normal script in the workspace.

01while wait(20) do
02for i,v in pairs (game.Players:GetChildren()) do
03wait(0.6)
04H = v.Character.Humanoid
05if H.WalkSpeed > 16 then
06print(v.Name.."also known as"..v.Name:Sub(1,5).."has been caught exploiting. His or Her Walkspeed was changed to"..H.WalkSpeed..". They will be kicked shortly.")
07wait(5)
08v:Kick()
09print(v.Name.."was kicked. Play fair, don't exploit.")
10wait(5)
11else
12wait(0.6) --to prevent lag
13end
14end
15end
16end

Actually changing the walkspeed directly isn't a very common way to speed hack. http://wiki.roblox.com/index.php?title=Stop_Speed_Hackers Perci1 4988 — 10y

I can't open that link, would you mind summarizing that for me? yoshiegg6 176 — 10y
