Subnostr

Here is a real example of how spam detection can help reduce noise on the Nostr network.

First image as I was enabling it. Semi-staggered in two phases.

Second two images are examples of relays (not finger pointing.. just examples) where their event traffic dropped 80-90% by volume (when I dropped the spam).

A few more examples. Including the Damus relay, which had a 52% total volume reduction.

Basically all spam detected was with 99% confidence or more only.

This stuff all adds up too. I found one specific spam event (duped, unique event_ids) I had stored 360,000 times on my relay 😟

Interesting there are a fair few relays where the traffic didn’t change at all - basically not being used by spammers (or syncing from a relay that is).

what was nostr.mom numbers two days ago and today. (I did spam filtering yesterday.)

I don’t have the specific data, however your relay volume in general reduced significantly from two days ago. I’d guess it’s likely related to your efforts. And your relay didn’t change after I applied my spam filtering today.

And here is Nostr global feed before and after spam filtering.

Nice, actually those keywords can also be used for keyword filtering in nostr client. Unfortunately, probably most client haven't implement this basic feature yet 😅
