>>4034029Saviorfags and concernfags are to different types of people:
A saviorfag is the end result of numberfagging. They only really care about the vtuber's performance. As such they will stick to a vtuber that they aren't a fan off because the vtuber has low numbers, and immediately drop them when those numbers become too high.
A concernfag is already watching the vtuber for the vtuber. They are too invested in the wellbeing of the vtuber, to the point where it may feel like they believe that they have a "real" relationship with them. Concernfags do not care about numbers, unless the vtuber shows some signs that their numbers bother them.
Let me put it like this to make mybpoint clearer. Aki, who is known to be a rather well adjusted vtuber, has saviorfags. Korone, who known to have a large viewership, has concernfags.
