You can do it. I use a powered USB hub and a raspberry pi, and 5 hard drives.

It is a mess of cables but was simple enough.

I also sprang for a UPS because most filesystem’s I tried like zfs and btrfs didn’t appreciate random brownouts from running 4 drives off the pi itself.

Right now they’re xfs and used for a minio install and torrent storage

The lemmy devs would probably take something sensible like that and flat out shoot it down because they think they know better.

I’m going to keep this in mind, I’m working on a similar tagging API

I mean, delta.chat exists…

The other way would be a dht of hashed email addresses or hashed keys, but then you could look up live email addresses to send spam to.

The magic of tor v3 is that the plain address record is needed for some time based calculations about the dht record, e.g. they publish the descriptor’s of the site using the public key as a reverse lookup

But that wouldn’t work to obscure the email or use the email as a lookup because the dht wouldn’t have a way to prove the record was true to that email, unless it was sending emails from it

I guess that leaves DNS records or some kind of activity pub system with webfinger
