>>86894970Youtube subscription is one of the lowest metrics of engagement really. There is basically no 'opportunity cost' in terms of capital - even viewership means spending time viewing that particular content instead of anything else. You only need to make an impression once to get a subscribe, and then it stays even if the users attention wanders elsewhere afterwards. Removing it means manually going back to remove it themselves, which 99% aren't going to do unless prompted by something (like major dramas).
And so, since you only need to make an impression once, subscriber counts are naturally most influenced by the most immediately obvious factors of a streamer: voice and appearance. And kronii has both a distinctive voice and model; and so she gets lots of subscriptions, even if her personality is the dog's bollocks and has comparatively little engagement otherwise.
