I met this guy in game trying to sell me in game items for mana. He told me he had proof of trust and showed me his profile on an item-selling website. What's more is the item he's selling on the website is the same item I saw in his tavern. Also, his name on the website is the similar to his steam name. This guy is asking to be banned...
