I'm trying to offer you the opportunity to give some reasonable explanations (such as, what the transaction between SmokerFace and yourself was), however so far you are passing up that opportunity with quite irrelevant jibber jabber in my opinion.
I don't remember exactly what this transaction was for, but I've traded altcoins with the person and even took loans. (Smokerface isn't the only person I've traded with like I said).
If you specifically want me to tell which altcoins?, then I don't know which it was - If someone had questioned me this when they were tagging Smokerface, and this blockchain question was raised, then I would've answered it, but now, it's not feasible.
So you have no chat logs, no PMs, no public posts or threads that you can go back and look at for reference? Usually when two completely separate individuals trade with each other, then communication is involved? Plus, don't you think it's quite a convenient time to just forget about the details of this trade? The most important question for yourself is, if you were on trial right now, do you think what you have answered would imply guilt, or innocence?
I don't keep history for occasional traders, but I might still have access to the address he sent the funds. (I will have to check), I don't want to reveal much about how I operate my trades, but I am afraid there's no data left of this user, to give (If you or someone else asked me this before, Then I might have had for sure given it) - But why didn't anyone ask me back then?
No, the guy deleted his account. So, I had to close the chat.
