strfry doesn’t spawn the plugin once per note, it spawns it once and streams notes to it via stdin/stdout
Not "noDes" but noTes. When strfry sees a new note, it sends it to the plugin you specify in the config over stdin. The plugin executes and responds back over stdout. In other words, unless you write to file, the Map that holds track of the sources will not be persisted for the next note (or the next execution of the script). The sources I refer to is this: https://github.com/damus-io/noteguard/blob/master/src/filters/rate_limit.rs#L16
