Interesting, not sure if it's actually active or just for testing. Seems to be a Lemmy software version behind.
Without any linked instances (http://kulervod.i2p/instances) can you even browse the rest of the Lemmyverse? Maybe this specific I2P instance is just meant to be tested/used on its own, disconnected from the rest of Lemmy.
EDIT: Being on I2P I guess it also seems to attract the expected trash users that gravitate to more anonymous social platforms judging from the test post/comment there.
As I understood instance in i2p can only federate with another instances that are in i2p. But maybe there's solution to connect to Lemmyverse maybe outproxy or a mirror in clearnet.
Theoretically you could just run Lemmy on a server and then setup a i2p address that points back to the Lemmy instance.
