I think your investigation does not make any sense, and I will explain why ... Looking through the history of airfinex messages, I noticed a few phrases in French, but obviously he speaks Russian and with all this he says goodbye in Swedish or Swiss (although I'm not sure what it is Swedish phrase).
In addition, his frequent quotes with reference to Theymos' words about confidentiality as an argument make me think that this guy is not an idiot and added this ETH address just for a diversion. If so, then you wasted your time on this investigation.

I'm not going to get into the Ratimov-airfinex argument, as I'm only recently learning what happened, but I agree with you that airfinex is anything but dumb. He's quite clever, and while we won't be able to know for sure, it seems quite plausible to me that he added the address to mislead. He doesn't seem at all like the typical bounty-hunter shitposter who usually gets caught by lovesmayfamilis for ban evasion for having used the same or a clearly connected address.
