He was interested in 7 games and gave the list of "MrFortyFive".
He also used almost the exact same user-icon as "MrFortyFive".
I called him out on that... he never replied. I also contacted the the user MrFortyFive just to make sure he/she didn't use another account which looks the same, but MrFortyFive told me he/she did not contact me for that trade.
It's always a scam when the 2 usernames differ in 1 character and the same icon is used. I just ask just to be sure.
(Unless the original user made a second account which is almost the same as his/her original account for backup purposes. But that's very unlikely in my very humble opinion)
Ooh, I had never noticed the 0/o thing when checking up on him (AFTER I got paranoid and called it off). Thanks for clarifying. And thank you subconscious for "pulling out"!
