correct approach for NOSTREAM
others should mirror their code once u do
- time gap between reply
- age of npub
- frequency of reply or new on the SAME relay
(no human can do this within secs - even telegram discord have this control )
then final hammer WoT or POW is always there now MOST relay software
The problem is that addressing it at the relay level won’t work because the spammer is sending brand new npubs and different messages to a bunch of relays. Nostream already blocks a single IP from sending too many messages in a short time but let’s be real most relays aren’t Nostream and poor rate limiting.
