The thing is, the Fediverse, link the original concept of the Internet is flexible and can survive losing nodes - it just routes around and issue. If there are problems it can mutate and survive.
I’m not sure if there’s a solution here, but I’d like to urge people to avoid lemmy.ml hosted communities in favor of communities on more reasonable instances.
This is the best solution - the answers are in our hands. Communities only thrive because the users are.posting and interacting on it. If the Mod goes inactive or an instances goes down, we can switch to a new community. That then gains the momentum and goes on to thrive. It’s survival of the fittest and why having more than one community on a topic (especially big topics) is a feature not a bug because it gives the network flexibility and resilience.
So if there’s an issue with lemmy.ml, boycott it - unsubscribe, give the other communities on more agreeable instances your time and they will grow and prosper. If there isn’t a relevant alternative start one.
