I'm just going to throw this out there but i believe there is POSSIBLY a private dupe method still working. I saw a spam name wizzy with 2 pyra in inventory in uswest2, saw him about 40 minutes later with 5 pyra. He could have possibly just been buying them from somewhere, or he could be duping them. This was about 4 days ago, too. Obviously no where near solid evidence but he was in uswest2 in a dead time, there was no one there - Plus he never had anything in his inventory that he could have been buying pyras with, plus never actually said a word that would indicate him buying them.
All this really points to is either a really slow, possibly luck related dupe to go from only 2 to 5 pyra in nearly an hour, or he could just be a d2jsp user buying and selling, could be buying from guild, nothing solid really... Just something to keep in mind and keep an eye out for though.
With that being said - No one would EVER in their right mind give you that dupe method if it did exist.
