Does she speaks Russian language, if yes then hopefully she would come up with the right proof. I trust and respect lovesmayfamilis for that.
I guess yes, she does.
@OP, do you have any other evidence to back your claims? It is really hard to convince everyone by just matching a word to connect an alternative account. I do not speak Russian and I don't know what the word is. The translator seems showing nothing. According to you, the vocabulary studied by everyone, could you please refer to any post of your locals where they have posted agreeing that he is the same guy? If so, then there is a better chance you will find other evidence. But just matching a word is not enough to say who is who.
