@LollerCorleone What I understood was that the moderation was difficult now, due not only to the size of the instances but also with the fact that almost all the people were new and the communities are not stable yet.
Since they have a quite high moderation standard, I guess that now, with few resources and a fast grow, it is difficult to keep it. And this standard is a commitment to the own community, people joint the instance because of it.
Another issue to take in account is that the moderation tools are not enough to handle with the problems of big and heterogeneous social networks. If I understood, in Lemmy and Kbin the only possibilities are to be federated or not, but not something in between like in Mastodon (the silence option).
