@skullgiver @Fonz It is possible; you have to set it up yourself and you won’t federate with many places.
Hosting Lemmy or Mastodon on Tor or I2P isn’t hard; you just host it, and link your Tor/I2P daemon to it same as any other website. But you have to be aware you’ll be cut off from the majority of other instances. You’ll be running standalone.
I am not sure about Lemmy, but Pleroma supports feeding all your federation traffic through a proxy; you can use one called fedproxy to split out your I2P federation traffic through your I2P daemon, and likewise for Tor. I am not currently running this on my server. It should still work for other fedisoftware than Pleroma. https://docs.akkoma.dev/stable/configuration/i2p/
@skullgiver Yes, there are many ways to make sure your server connects to Tor and I2P sites. But that’s what the guy who ISN’T running a Tor/I2P site has to do, to federate with the Tor/I2P site. If you’re running the Tor/I2P site you can’t really do much on your side to enable federation.
Cloudflare won’t help because you need inbound connections. Some VPNs support *transient* port mapping designed for BitTorrent, but good luck trying to claim a stable port number for any significant length of time, never mind port 443 (which I’m sure is outside of the allocation range anyway). You’d have more luck trying to find a VPS provider crazy enough to let you pay anonymously with cryptocurrency with just a pinky promise that you’re not hosting child porn. Or just don’t federate.
