Hi Kieran
Thanks for reaching out. I am not involved in the blood collection, I just tried to help someone who ended up dying unfortunately and discovered some flaws in the system. A community was created because of it and some changes have been made but I am not super up to date on the situation.
The community we use more often is Facebook (Blood Connections) although it isn't super active these days. I would say just go into a donation center and see what happens. If you don't speak Korean bring someone so you can understand what is going on.
