Nostr was very cool until the Chinese flooded in spamming ads and wechat links. Anyone can let me know how to filter them out? It is around 95% spam at this point.
There are really 3 ways to prevent spam reliably in a "global" system, ie a commons:
  1. algorithmically, e.g. bayesian spam filtering, ... a constant arms race
  2. [transitive] reputation, e.g. WoT
  3. making it expensive
The more of (1) and (2) you can use, the less of (3) you need. But you probably want all of them at scale.

There has to be a fourth option

I just tend to avoid the global feed and stick with my "following" feed. There is also probably a way to add and remove relays to help the situation, but I haven't tried that yet.

You need the latest Damus version from testflight (if you are not in the testflight beta, wait till this version appears in the App store).
This version by default only shows paid relays on the global. So then you just need to purchase a few. I bought the same ones as Jack Dorsey:

  1. Use paid relays.
  2. Use https://nostrgram.co (reads from paid relays by default)
