This is a repeated thing, despite what others say. There was Ivan most recently. There was also Takaki who was a reputable seller from Singapore who up and disappeared one day with a large pile orders unfulfilled. (And of course, Gutz bemoaned publicly how he was from the same country. To be fair, nobody knows what the hell happened to Takaki. I bought a set from him with no issues, as well.) There's plenty of incidents of people falsely advertising their goods as being "mint" or "perfect" and actually being beat to hell or just flat out broke.
None of these people have suffered any real consequences. Even when it's known they've been banned from other forums for it, they get to sell here. And rarely they'll get 'banned from selling' after the fact. Banning someone who already scammed and ran from further sales is as useful as pissing in the wind.
That's why they keep coming to GH. They know that not only will it work, they will get away with it.
