If you have, or want to post a new community, you might want to add it to Lemmy Federate too. This way loads of servers’ bots will automatically subscribe, and the communities’ posts will show up in anyone’s “All” feed on the participating servers (of which there are loads).
It was linked with fediseer and was configured to only work with endorsed instances. I’ve disabled the fediseer option. I hope it works better now!
