Hello (owo)/
This is just an idea but I think we should set a rule where if a dancer or dance group is inactive for a year and has not made an official disbandment announcement that they will be considered inactive as a group.
I've been starting to notice some pages that the dancer(s) haven't uploaded or have done any activity under that name in over a year so I think that its safe to say if its been a year and they have not done any new works they will be considered Inactive as a dancer/dancegroup.
