If a remote event gets fired, when the server picks it up there is a player argument:
RemoteEvent.OnServerEvent:Connect(function(plr)
end)
But is there any way for exploiters to fire a remote event, and change the plr argument / pretend that someone else fired it?
No, I don’t think so, as exploiters can only do their exploits locally.
They cannot. The player argument is grabbed somewhere by the server so it is impossible for an exploiter to fire on behalf of another player.
What if an exploiter does this:
The post is not talking about being able to spoof requests as another player. It is impossible for exploiters to spoof the player argument. Like it or not.
