paid relays + free relays
paid relays only for global to avoid spam.
look at nostr.wine it has a very interesting filter.
https://github.com/nostr-wine/filter-relay/blob/main/README.md
And how can you configure certain relays (paid) only for global messages, and others as not global (and what do non-global relays do then?). Better example for Amethyst
Do I understand correctly that paid relays relay posts only from those who paid them? What is the point of using them if most of the information from normal people (who did not pay, for example, to eden relay) does not reach? And if you add at least one non-paid relay, spam begins to go into the search tab of Amethyst.
Last night I used only Eden paid relay (I paid there). At morning many posts in my Amethyst are missed: many profiles like npub:xxxxx, no spam but no normal messages too
Browser history?
I don't want to change all free relays to paid relays only because the Amethyst shows all posts when tab is magnified icon :)
The problem is that there is a constant stream of spam in the form of images that are constantly being loaded. At the same time, private information leaks out: the client's IP address of Amethyst. In addition, very soon spammers will start to make a DDoD of sites in this way - instead of pictures, they load the resources of other sites or increase attendance at the expense of Amethyst customers who decided to search for something in Amethyst.
#[0] The magnifying glass icon is annoying because there are constantly spam posts. Unfortunately, creating an account costs nothing, which is used by spammers. But it seems to me that in the search tab it is not necessary to display all the current posts from the relays. It's even dangerous.
Seriously, yes, there is something. I watched the tape for a few minutes and the Amethyst began to work slower and slower until it closed. Fresh version - 0.15.*
What is boosted? And why 4 days old posts are in top of tape? #[0]
