There's a NIP for that already, and using it would stop an attack this primitive in its tracks 

 Users who are concerned about more sophisticated attacks could also benefit from adding context to their social graph so that the context can be factored in to their WoT calculation 

 Spammers have better resources for PoW than the average mobile user 

 Indeed, this is a tricky problem... Perhaps we will need to accept a combination of multiple approaches with their trade-offs. 

 Absolutely! 🚀 Nostr is a cool way for newcomers to dive in. No need for complex stuff. Just keep it simple and fun for everyone! Let’s spread the word! 👍✨ 

 I'm a walk-in newbie, no sats. I like participating. Proof-of-Posts/Participation(Work) is the way forward.  Go beg/borrow/study FUTO's harbor social vouching process and see if there is something to learn or cooperate with their collaborative vouching model... I think it all depends on the network effect, so nostr will ace that, but FUTO has grayjay aced... So many wheels to reinvent. 🤔 

 How would you limit write access then? Storage and bandwidth are limited, and will be filled with spam unless you limit write access somehow. 

 I just told you. Give users client-side more sophisticated solutions that allow them to curate their feed by themselves. Right now I can mute words, works OK at the basic level. Being able to block regular expressions would be even better. 

 Blocking by regex would be dope  

 FYI, because I set the minimum WoT score to 1, I missed this note at first. 

 Spammers would just start producing variant messages that won't match a regex 

 It was just a very simple example of an improvement that would require little cost while empowering users and respecting their freedom, compared to the false solutions commonly discussed. 

 How to solve it on the relay side without blocking newbies? 

 I don't want any relay-side "solutions". That's what would make Nostr unsafe to use and, in fact, threaten its very existence. 

 Storage and bandwidth are limited, you can't give unlimited write access to everyone. 

 I hope we can do p2p between clients in the future, skipping the relay part 

 That would be my absolute favorite option. But as long as we run on relays, I want relays to do exactly what their name says: to relay. They're not called "filters", "funnels" or "publishers".
