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.
