Duping on PPOFollow

anyone with toons on PPO be aware that the characters Despayre, hateyou, everstupid, ubahresist, thefiremage, and others have found a way to dupe items and have been selling them on auction and trading them to people. if you have bought an item from them in the past 184 hours or however far back they have logs for auctions expect to have felthius popping up in a tell asking for a minute of your time, but atleast he will give the tunar you spent on the item. anyway you have been warned :)

How you know they made copies of those items?
