I have blocked the spamny 70202 kind events on my relay. I have probably seen well over a million such events lately. Created a PR for nostr-rs-relay to be able to blacklist certain kinds: https://github.com/scsibug/nostr-rs-relay/pull/36. Come tear this small PR apart!

Nice!

Oh I just saw this. Thanks for the info once again!
Interesting, thanks for adding this and bringing it up! Although, my relay doesn't use nostr-rs-relay currently, I wanted to see if this was available in nostr-ts-relay/nostream which is what my relay runs and I was surprised to see the option there. I'm going to try adding 70202 there and see how it functions. Is there an example spam message that you are aware of that uses this event 'kind'?

Oh cool, nostream has POW limits on events, TIL
