Sorry for your loss but I think it would be more appropriate to send some factual evidence regarding the scam to @ethan_nx or to the support in the website itself. As far as I know, trading or any other similar activities is unmoderated and they are not liable for any loss committed from their players. Also, do not easily trust a stranger especially if a large money is involve during the trade because there is no guarantee that there will be a safe place especially on the internet.
