You wouldn't know if he knows of the dupe methods, because if he did, he wouldn't just tell everyone. And it's very easy to find on google also.

It's far less likely he could actually figure how to cheat if he doesn't even know how to dupe. I don't even know anyone myself who can actually just cheat (as in, hack) in a server.
