No big surprise here, the HyperNet Relay is chaulked full of scammers. One guy put a Vanquisher up, bought 114 of 512 Nodes and walked away with the Vanquisher and 233b ISK. Green offers aren’t even guaranteed to be a “good deal”. Do your research before you buy those lottery tickets.
I see a lot of people putting items up for 200% of their cost and buying half the tickets. 50/50 they will break even OR receive the item and 100% of the cost. Pretty sad really.
