Due to lemmys focus on communities instead of individuals it seems like some level of centralization is going to occur or already has. As an example !privacy@lemmy.ml is going to be a way more active community than !privacy@somerandomserver.org. now if i run a terrible server called terribleserver.net and lemmy.ml bans it as they should then nobody on terribleserver.net will be able to interact with the largest communities such as !privacy, !technology, etc. Other servers may have their own versions of these but they will most likely be rarely used. Mind, i doubt lemmy.ml’s mods would do this, but a rogue mod could really break things by just banning other instances for no reason. I have been on mastodon for years but am decently new to lemmy so if i am misunderstanding this please correct me
