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?
Federation.
There’s a reason why worldnews@lemmy.world and worldnews@lemmy.ml are not federated with eachother, yet lots of users are subscribed to both.
For lemmy, it’s again a federation thing. You just don’t see many multiple defederated examples due to the small user count.
It’s not the most optimal solution, but it’s still miles better than dealing with single instance or single community issues.
