2 times today on both w84 and w2 there are players actively manipulating bond prices. spaming mass buying of bonds at 124mill. this needs to stop. it's getting a bit out of hand.
They are most likely trading items that are overpriced on the GE. So even though they show up as 124m worth of items, if you actually try to sell them after it might only be 1/10th of that price.
Somewhat related to that; other players will enlist your help in buying some item or another. After a couple rounds of honest trading they will ask you to buy an overpriced item, which of course they are selling.
The bottom line is don't deal in any items unless you know how much they are actually worth. If someone wants you to buy something, consider that you might be stuck with that item.
