Do people see a lot of spam?? I am not even sure I get 1 or 2 a day. Compared to other platforms or X, that's childs play.
for now, spam is okay-ish. But if one note can pass the filters, it means millions of notes CAN
Very nice!
I am already enjoying a distinct lack of spam in my Nostr experience by other means. Mainly not using #Primal and making use of relays that filter it by various means. That and using #Coracle's built in WoT scoring, which can differentiate between someone having no reputation (score of 0) and a bad reputation (score of -1 or lower).
How does this distinguish between those who are maybe new users, and therefore don't yet have a reputation, vs those who have a bad reputation, because they are spammers or often muted by reputable nostr:npubs?
very good questions! Coracle counts how many follows/mutes, but doesn't differentiate between the importance of each one.
For example, a follow from someone that follows 5k npubs should have less impact than one from someone that is more selective.
Our approach is using Pagerank (Global/Personalized), which has nice properties (like the one above), and allows for pre-computations that massively speed up the responses.
However, Pagerank has a strict interpretation as probabilities, which cannot be negative. This means that as things stand rn, we can't differentiate between a spammar and a brand new user. However, if the new user gets few reputable follows, he's already connected. Hope this answers your questions
Turns out we already have spam filters and you're just adding to spam.
Are there any clients currently implementing this, or is there another way to access this DVM? I don't see it in the DVM feeds on Amethyst, for instance.
@Zapstore is using @Vertex to verify the reputation of app developers, minimising the risk of impersonations.
As for amethyst, wen Vertex @Vitor Pamplona 🤪
