Well I don't see why it would be popular in asian countries since this site is aimed at people who needs translations for asian media
The people that live in asian countries doesn't need the english subtitles

so normally they'd use other sources.
My cousin, who came to the US not long ago, still uses her chinese sites to watch stuff; I have to admit, the chinese sites have a far broader range of media compared to any english site I've seen; that includes japanese animes and stuff

also, the chinese subs come out way faster too
