Yeah, if DVMs are not available, I think it would be best to start marking users as "interacted with before" and then filtering by those. Meaning, you have to have liked or replied to the person before to show up on notifications.
Which is very similar to how we separate known from new people on DMs.
Meaning WoT from the reply/like/zap information, not only from the follow list.
Exactly what ive been thinking, except in my design these are inputs to a pluggable nostrscript anti spam algo
Nice! I might start creating a User Status event for every new interaction, putting them into the "interacted with" list
