As you, educated people know, we can notice a grammatical error in Yuki's Engish. In British English, Hong Kong English, whatever, 'text with me' is incorrect, it is just literal translation of 跟我連絡. Hence, it is reasonable that people may think English is not her mother tongue, any native speakers can speak/write own mother tongue incorrectly though. This is what I wanted to say, I don't intend to blame on Yuki at all.
What we call as mother tonguer or native language is not based on where people lived or grew. It is the first language that you learn when you are a baby. Even if Yuki was born and raised in Hong Kong, even if her 母国語 is English, her 母語 can be other than English, like Cantonese, Japanese, Russian...depending on her invironment. The troll should understand that instead of insulting the others.
Perhaps, above troll with poor Japanese is a same guy who posted 中共管理員返回中共 at BBS, labeling site manager as 神経病, 笨蛋 (it is now cancelled by manager as many of us reported). Anyway, who is a real 荒らし? Yes, such people who post offensive responces. I am sorry for lack of education, loneliness, aggressiveness, etc but I really hope they will be banned.
