The more normal transfer path is to offer to take over a specific community or communities by:
- Reaching out to the existing mod and asking to be added to the mod team.
- Documenting their lack of response after a few days or a week.
- Documenting the failure to abide by Lemmy world moderation guidelines: https://lemmy.world/post/424735 by linking spam or off-topic posts and to communities that lack rules/useful-sidebar-content, etc.
- Posting this info in !moderators@lemmy.world and offering to takeover moderation.
This is better than mass deletion because it keeps whatever small list of existing subscribers and post content intact across the transition. For moderation, Lemmy world admins will get notified of reports and can address anything that violates instance rules.
