This is the nil prevention system that Epix Incorporated Server Suite admin has
1 | Pcall(function() if set.AntiNil and (not set.CheckAdmin(p,false)) and (not set.CheckOwner(p)) and (not set.CheckTrueOwner(p)) and (not set.CheckExcluded(p)) then Pcall(function() p:Kick() end) set.Remote(p,'Function','KillClient') for k,m in pairs(workspace:children()) do if m.Name:find(p.Name) then m:Destroy() end end end end) |
The main script gives a player a local script named client when they enter the game, the local script then nils itself and continues to receive and send signals to the server. It appears to me from the script, that when a player leaves the game then the script checks if you're a admin or not. If it registers you're not an admin then it will attempt to kick you then crash you if it fails.
It appears that Kohl's Anti Exploit script, uses a similar technique
01 | if not select(2, pcall(Workspace.GetRealPhysicsFPS)):match('GetRealPhysicsFPS') or |
02 | game.Players.LocalPlayer.Parent ~= game.Players or |
04 | game.Players.LocalPlayer.Archivable = true |
07 | game.Players.LocalPlayer.RobloxLocked = true |
If the script is able to change the RobloxLocked property, or not be able set archivable to true, or the player's parent is not in game.Players, or the script can't register the GetRealPhysics Property (It's partially a anti speed hack script), in two or more of these cases, then the script will crash the player.
I am not sure if it is possible to use ServerReplicator for something like this, but I have not researched many anti exploit scripts to know for sure. You can try out the Kohl's Anti Exploit, or Epix Inc Server Suite admin, they both provide these options.
