As the title says
OP starts:
Any fans of nugu groups: props for supporting your faves.
Once: Have had lots of wholesome interactions with them. Twice has lots of funny content and they are always happy to share.
Carat: supportive and get in relatively few fanwars for how big they are.
Blinks: support their faves and are accepting of their choices. Don't have problems with their faves dating.
Orbit: good job supporting the girls instead of the company
MOA: Seem chill on the whole. Always happy to share good music when asked.
Stay: happy to do charity projects and support good causes.
Bunnies: Energetic, relatively new fandom. Is nice to see them grow.
Insomnia: Never had a negative interaction with anyone. Are happy to invite even casual fans into their fandom.
As for Day6 and Infinite: I didn't interact with any fans before I joined this forum, but they have some very positive kind fans here that I always like hearing from. I have added music from both groups on my playlists.
(so this is not meant to take digs at other fandoms under the guise of compliments. It is about being nice. Try it )
