This guy actually scammed me today with his so called "nvidia pick your path code". I sent the tf2 keys first as he had higher rep than me, then he gave an invalid key and immediately went offline, by blocking me on steam too. If you look at the Nvidia redeem page which is also in the screenshot album, you can clearly see that the key he wrote does not even fills all of the spaces. It suppose to have 6 divisions containing 4 characters each, but this one has 3 divisions with 5 characters, like an ordinary game key. He literally copy pasted an invalid key and left, I did't even have time to write him back. Here is the Chat SS
Fast, friendly and polite. Trusted him with a 4-pack and he came through. Would love to trade again. +REP!
