TRADBLE ITEMS DUPING?

hi so recently i started hearnig alot about flux/items duping i want to know if there are any methods that are actually working or no.

I would honestly like to find out dupe methods also, mostly to dupe chaos chest and golden pitcher seeds, but... I doubt anyone wants to share stuff like that publicly or share it at all in fear of it getting patched.

It is most likely known to a select few and that's how it will be unless you are able to join the "in group". Would love to join said group but I haven't even the slightest idea on where to begin.
