Got the same one. To be honest, it raises so many red flags it just has "scam" written all over it which is quite a shame if it is indeed a legitimate offer, but it's so impersonal it seems like they're just sending it to as many people as possible. Usually not a good sign. It definitely appears to be spammy, not to mention many artists here might not feel comfortable with what they're asking for...
Anyway, I don't know a single word of Korean, making it pretty difficult to do proper research. The few Google results aren't helping, haha. So while I'm extremely wary and I'd advise anyone to be careful, I'm also not entirely sure if reporting it as spam/a scam/whatever is the right thing to do. For all I know they could indeed have every intention of paying the people they hire.
