Are you accepting contributions yourself? I took a lot of inspiration from your code to create what I'm working on. Most of it doesn’t make much sense on Android (for example, I’m managing Cloudflare tunnels and running cloudflared as a subprocess to expose relays behind NAT) but I also have some features that might be useful, like restricting writes to people you follow, or to people followed by at least three people you follow. There’s no UI, and I’m not using Room/SQLite for my own stuff , but I’d be happy to try separating the “in-memory” WoT model from what I’m building and contribute. This is similar to what Haven does at the moment, using an in-memory WoT map. As simple as it is, it works quite well against spam for folks exposing relays publicly (as I'm sure that some Citrine users are already doing).
