check the dates.
The Xenonauts steam key he traded me got revoked a month later. When I contacted him about it, he unfriended me and changed his profile nick. Also has a potty mouth. [Edit: actually he unfriended me before I contacted him about it. I remember now, since I had to leave a post on his profile instead of sending him a message. After I left the post, he immediately changed his nick.]

Good trade. Responds quick and trade was set up within a day.
Edit: 10 months after the trade the key was revoked. http://i.imgur.com/OiGsv0y.png
