Hey, sorry about that :( And I do got your point about backups.
Although, in retrospect, a backup setup with relatively fast rotation,
and thorough deletion of old backups, would be prudent.

As I said, shared hosting is a security nightmare. As I understand it,
you're depending on not much more than permissions to protect users from
each other. And in that situation, it's not _that_ hard for a skilled
hacker to get root, and do what they like.

If I were going to attempt such an .onion hosting setup, I'd use a
couple levels of isolation between users. But first, I'd use LUKS with
dropbear for server FDE. It ain't perfect, but an attacker would need to
take some care while impounding the server.

Basically, I'd setup several KVM domains, to help limit damage from a
compromise. Within each domain, I'd put each website in a Docker
container. Given a custom Docker-optimized kernel for the host, and XFS
storage, it's possible to set hard limits on CPU, RAM and storage for
each Docker container.

Docker containers rely on kernel namespaces and cgroups. That's not as
secure as using full VMs, but _far_ lighter. And _far_ more secure than
chroot, which many shared-hosting setups still rely on. Alternatively,
one could use FreeBSD jails, and maybe that can also work with Docker.

Anyway, if you're interested, I'd be happy to help. I'm just a hobbyist,
and totally self-taught. I mostly just use shell scripts. And I lack the
patience and organization to actually operate a shared-hosting site.
