Yea look … diversity and decentralisation … these are good things (and things we can get better at)
But when you’re duplicating topics the onus has to be on you to make it clear why you’re doing and what the differentiation is. Otherwise we can’t trust that you’re not just making a community so you can control it and don’t want to “play with others” that already have an established community.
If mods have gone MIA … you can get the instance admin to help you take it over … there are other options, and you really should just try to clarify things.
Beyond that … if you’re committed … getting multiple mods ASAP (besides yourself) is probably essential.
