You can probably try using nfrelay.app . It has already spam filter implemented to handle RplyFamily and Impersonator. Let me know if you have still those spam while using the relay 👋
Additionally you can also add WoT relays to help such as:
- wot.utxo.one
- nostrelites.org
- wot.nostr.party
- wot.siamstr.com
- nostr-relay.app

Just suggestion, maybe you can add policy rule like this
https://github.com/atrifat/strfry-policies/pull/1
Policy that request external API that you can freely implement later to process the event. I have done this nfrelay.app to filter RplyFamily and impersonator by reading metadata profile.
Simple Policy API server example can be made like this:
```
const express = require('express');
const bodyParser = require('body-parser');
const app = express();
const PORT = 3000;
// Middleware to parse JSON bodies
app.use(bodyParser.json());
// POST route for /spamfilter
app.post('/spamfilter', (req, res) => {
const { input } = req.body; // Destructure input from the request body
const content = input.content; // Assuming content is a property of input
// Simple spam detection logic (for demonstration purposes)
const spamKeywords = ['spam', 'buy now', 'click here'];
const isSpam = spamKeywords.some(keyword => content.includes(keyword));
// Respond with { accept: true } or { accept: false }
if (isSpam) {
return res.status(200).json({ accept: false });
}
res.status(200).json({ accept: true });
});
// Start the server
app.listen(PORT, () => {
console.log(`Server is running on http://localhost:${PORT}`);
});
```

This Reply spam seems little bit different than regular RplyFamily. It was targeted to more certain users (popular users).
I think we need more "Smart clients and Smart relays" here to solve the issue. Clients can show it clearly when the person have invalid NIP-05 (impersonators) while relays might probably filter them out.

Welcome. Yes, it is read-only aggregator relay for now. I will prepare it later so it can also accept write directly and handle spam better. Let me know if you have problems or other questions 🙂

2024-09-15 05:32:51

1. It will be used by Amethyst to fetch event but will not be used to publish event into it. "Read" relay or Public inbox relay in amethyst relay settings. You can set it in "Public inbox relay" or you can set nfrelay.app in "General relay" setting like this:
https://github.com/atrifat/nostr-filter-relay/blob/main/resources/relay-setting-amethyst.jpg
It should have same effect.
2. nfrelay.app will fetch other posts/notes from other relay automatically in my server. It is ok if you dont set nfrelay.app as "write" relay. nfrelay.app is a read-only relay actually.

2024-09-15 04:22:57

- reply

Yes, you can set it as "Read" relay Kohei-san. To set "Write" relay, you can use any other major relays and notes/posts will be aggregated into nfrelay.app .

2024-09-14 22:50:34

- reply

Do you aggregate events from nos.lol to relay.nostr.wirednet.jp, Kirino-san?
If you need relay to aggregate global feed then you can try nfrelay.app . It aggregates events from major relays. Also, I have already filtered spam of RplyFamily.

Amethyst latest version also do good job with Filtering profile metadata based on "hidden word" that were set. Other clients like Nostur implement WoT.

Unfortunately, there is no specific setting yet to filter language in major clients. At most clients will directly translate into 'best guess' target language like Amethyst and Damus (Purple member) done.
Currently nfrelay.app provides NIP-32 event for language labelling. Hopefully more labeller comes and client can pick up and choose data freely.

#NostrFilterRelay v0.4.0 update
"Compatibility bring various apps grow together" 🌱
This release bring important change with NIP-32 compatibility (kind: 1985). Starting from this release, legacy custom event (kind: 9978) that were used for classification data in nostr-filter-relay has been deprecated. Other #nostr apps can freely uses NIP-32 label.
Legacy support is still available by setting nostr-filter-relay with environment variable as follows:
ENABLE_NIP_32_CLASSIFICATION_EVENT=false
ENABLE_LEGACY_CLASSIFICATION_EVENT=true
USE_NIP_32_EVENT_FORMAT=false
Explanation of NIP-32 structure were documented in NIP32-COMPATIBILITY.md . Thank you @npub1jlr…ynqn for valuable discussion 🙏.

Client and relay can implement some content filter feature.
For client, especially web clients, can use these libraries to implement the feature easily.
https://github.com/infinitered/nsfwjs
or
https://github.com/NsfwSpy/NsfwSpy.js
I think there are other libraries for iOS and Android that can be easily included in native clients.
I have already implemented in relay code of wss://nfrelay.app which gives filtering feature to its users.

I see. Glad to hear then.
What do you think about multiple label "l" structure that i have shown in language or topic labelling? Do i need to change something in those cases?
Example:
Note/post which has multiple languages
["l","en","ISO-639-1"], ["l","ja","ISO-639-1"]
Note/post which has multiple topics
["l","science_and_technology","app.nfrelay.topic"], ["l","arts_and_culture","app.nfrelay.topic"]

2024-08-09 01:09:01

- reply

Thank you. I think i want to make sure about label namespace.
Is it ok to state "L" namespace multiple times as long as it was clear which reference of the namespace? In language labelling i made two namespace using "ISO-639-1" for public use (different apps/clients can freely query it) and "app.nfrelay.language" for internal use.

Yes, agree. Possibly with Freemium model. Free with short term storage and paid with long term storage.

2024-08-08 22:43:14

Not exactly same, i have little experiment to store only 7 days old of events. All events excluding main metadata event (0, 3, 10002) will be deleted if they were 7 days old. Metadata events were not deleted. It only takes around 10 GB of storage.
It was feasible plan for free relays to do something like this.

I see, it is quite hard for critical computation that need fast processing (< 100 ms) especially if the implementation can't be rewritten totally.
Based on your experiences, is it possible to generate zk proof for external API request? Or is it limited to computation that was calculated directly on host machine?
Examples:
1. We provide DVM that gives weather data that were processed from external weather Rest API service
2. Text Summary DVM that gives summary after request them into external AI service (GPT4, Lllama3.1 405, etc) due to can't self host it
Both cases need external service

Oh, I think many devs who are not familiar with ZK proof might choose second aproach due to minimum modification of the original code or they just can't due to all dependencies which hard to be rewriten all over. 😅

Sorry to hear that Quentin, thank you for your service. It is really hard to handle those issue as media service provider.
Maybe, you can take a look on
https://github.com/atrifat/nsfw-detector-api and might be modify it.
I've used that as module for nfrelay.app . It is effective and really help to handle the issue. Hopefully, it can also help you.

Not sure what is the answer for the first question, since my experience were limited to manage small-medium traffic relay (20+ GB/day). Maybe top relay operators will share their experiences later. I think top relays have big traffic more than 1TB/day.
> Hands on is sysadmin
Basic skills to manage linux or unix server such as configuring webserver (nginx, caddy, etc), setup proper firewall, ssh and account security, manage running service/apps (systemd, sysinit, etc), and basic linux/unix command knowledge were needed.
> Costs
Costs for running small-medium relay around $10/month . Varies depend on server provider.
> Preferred relay software
Currently using strfry. Other popular choices are nostr-rs-relay, nostream.

I use nak REQ to my local relay tray yesterday after sending event through hub relay. But, no worry, it seems yesterday I only have connection issue. It is ok, it works properly now 😅
There is another bug. Using v1.5.0 AppImage, with the following setting: Default block and only allow kind 1. But local relay tray reject all events including kind 1 that was supposed to be accepted.

Cody, I have tested v1.5.0. It works properly when requesting event (REQ) through hub relay. The hub fetch my local relay tray event. But, it is not forwarding event to local relay when i send event (EVENT message) through hub relay. Is it not implemented for now?

No, this is bridged account through Mostr. They also seems to only federated with several fediverse instances (blocked lots of fediverse instances).

You can probably try using Nostdress. It has Zaps support included.
