Whats with the Duping.

I thought duping was dead after the 10 minute loading screen... (i've been away from realm for awhile)
Is it back?
Where can I find information on how to do it? Thread link. PM me. Comment if you can.
Im aware of basic game/code mechanics.
Whats the success rate?
Any notes would be helpful.
I looked through several threads but found no significant info.
I did see something about only trade-able items can be duped. Also something about packeting the server. And also something about pre-oryx realm shaking.
But I found nothing actually helpful.

my pet hacks it uses autoaim

Packeting the server seems like a good tactic. I'd go with that one.

On a serious note: There are no public dupes, and no one is going to tell you how to do their private one if it exists.
