Lemmy is created as an alternative to sites like Reddit, Lobste.rs, Raddle or Hacker News: you can subscribe to topics that interest you, post links and discussions, and then vote and comment.
But there is an important distinction: any user can run their own server, which, like all others, will be connected to the same 'universe' called and interact with other services that support the ActivityPub protocol. To create an account in these services, you are advised to. A user registered on one server can subscribe to topics on any other server and can engage in discussions with users registered elsewhere.
Each of the Lemmy servers can have its own moderation policies and appoint moderators to combat toxic trolls.
Currently, a beta version is available, and many features are not functioning or are under active development, such as the federated network.
