It’s quite difficult for Channel Managers and I know these discussions as well. I don’t have that many channels and before I was appointed for Voice 4, I had to wait 3 years to be CM again. With 20 or more applications for just one language, you will disappoint many moderators, because you can only choose one plus co-moderation, if wanted.
I got applications, where the moderators claimed to be “The ONE team for this genre” and told me, that this or that moderator would be “very bad”. It’s difficult to choose someone, if you don’t speak the language and you don’t know their skills, but such accusations are not helpful at all.
So, I can tell at least for the German community, that we don’t have “that ONE team” for a genre or maybe some specials actors. We have moderators, who prefer Chinese or Korean dramas, some who love historical dramas or modern ones and some for the so hyped BL dramas. But not “that ONE”, even if you can find for some genres almost every time the same moderators.
