Best way to protect remotes?

So I'm trying to find some new ways to protect a game without using those anti-exploits which limits my creativity.

So I'm trying to know how to prevent from being executed by exploiters or hiding them that RemoteSpy doesn't catch them.

I heard using _namecall can prevent it but I didn't see a wiki on that.

I suggest indexing the remote at the start by doing something like this:

local rem = workspace.RemoteFunction;
local f = rem.InvokeServer;

And then when you need to fire it, pcall it like so:

pcall(f,rem,args);

Hope this was helpful.
