Thanks for the comparative analysis with notabug, that's interesting.

We are considering putting our database in a torrent file and updating it monthly, as a cheap way to backup and store things publicly. But all the PMs and private subs are unencrypted, and some users may not like having those made public, so we may try to encrypt those before making the database public with a torrent system.

I don’t log IPs, and currently run Cloudflare in front (so dont even see real IPs).

We also run cloudflare in front. But we figured out a way to gather the original IPs, which are stored in the packet headers. D3rr wrote a little program to track those, so we can actually block specific IPs in cloudflare with their free software.

I like your p2p replication model, it's cool. Hearing the details about notabug is very interesting, as we've been kind of operating in the dark in some aspects, as not many people are building this type of website.
