You talk about logic though and there was some logical thinking there for you. You said I posted a picture of two random guys. How can I post something so random when it's game we are playing? So the clue was there.
But they could have been posing for anything and even if it was clothes, it could have been for any fashion related thing in the word. And even given that you chose Joe Fresh (which I've never actually heard of) and you have to take just the first name of that, I imagine there is a high likelihood that there are other members with vaguely related usernames to other fashion resources also. I'm also not too familiar with Joe as a member so that also didn't help much XD
