This screencap originated from a secretive moderated membership (they stalk your background before they accept you by googling your username to see if you're a spy *gasp!*) forum dedicated to shipping a Kpop couple. Sounds pathetic? It is. It takes a substantial amount of money to run forums, you might be aware of this if you interact with admins of international forums or if you see the donation bars etc.
I wasn't aware of this but apparently some hardcore SEA shippers stalk idols after Kpop concerts to see who they interact with etc and to primarily find 'evidences' about their ship.
