Jlai.lu is a very small French instance, in order to coral our limited number of users towards more active communities the admins had made the decision a while ago to put into a deep sleep state any inactive community. They very recently created this dedicated thread where one can request the reopening of any 'sleeping' community: [Meta] Demande pour les réouvertures de commu + modération
A side-note and a suggestion for anyone considering requesting moderation role of an abandoned community on any instance:
Based on my personal experience requesting the !journaling@sh.itjust.works, I would suggest anyone to create an account on the concerned instance to administer that community. I can say that the admins at sh.itjust.works made no issue giving me full access to the community after I explained what I wanted to do with it, but even as a the new moderator with full access I had constant bugs and issues trying to do my job from my main account from my own instance (I'm French, so I was administrating that community from my jlai.lu account). All those issues, 100% of them, vanished the moment I created a new user account on the same instance I was trying to manage and gave that account full moderation role. I've also read other similar accounts of people facing bugs when they tried to moderate a community from a different instance.
A warning that may be worth adding in the OP?
