many services such as websites, git hosting providers, torrents, chats, forums, etc are available on I2P. But is there any Lemmy, Mastodon or other Fediverse/ActivityPub network on I2P? I am not talking about a proxy to clearnet Lemmy/Fediverse but a I2P Fediverse. Please let me know if they exist and where to find them.

sincerely, xxxb
