NYUUG pretends to be Korean. The truth is, he was born in America, is an American citizen, does not have Korean citizenship or a Korean passport and cannot speak Korean. He is living abroad like any other sad sexpat that was exiled from their homeland due to no romantic prospects. Since his ancestry is Korean, he could get Korean citizenship, but in order to do so, all Korean "males" under 35 must complete mandatory military service. Nyuug is a coward and won't do this, so he is still just another American sexpat loser and not a Korean as he constantly claims to be.
[John Linton] actually grew up [in Korea], unlike [nyuug]. And his family has been there since the 1800s. And he got elected to the National Assembly. He seems pretty Korean.
He makes his own Korea and poasts about himself with an alt, then bumps his own threads. It's performance art, admittedly a one-note variety of it. Nobody on XO actually cares about Korea unless it comes up tangentially because of Starcraft.
