It appears to me that the current state of Lemmy is similar to other platforms when they were smaller and more insular, and that insularity is somewhat protecting it.
I browse Lemmy, and it feels a bit like other platforms did back in 2009, before they became overwhelmed and enshitified.
If I understand it correctly, Lemmy has a similar “landed gentry” moderation scheme, where the first to create a community control it. This was easily exploited on other platforms, particularly in regards to astroturfing, censorship, and controlling a narrative.
If/when Lemmy starts to experience its own “eternal September”, what protections are in place to ensure we will not be overwhelmed and exploited?
I would suggest starting the invite process with the people who were in the community before it went awry. You can also make a post about how you’re starting a new community in the old community and explain what will be different in the new community. I belive this happened recently with the “196” community becoming the “oneninetysix” community when the mods made decisions the users didn’t like.
Being mod of the new community would allow for removal of unwanted users. Additionally, if you were admin of the instance, you could block other instances that had users that tended to not match your stance on issues.
Hopefully, that helps.
