Fighting to remove it from Nostr you mean. Nothing you do here can prevent child porn from being produced and distributed elsewhere. The ability to stop a crime always depends on the choices of the criminal, and the choices of the victim. The fact is that the criminal never needed permission from us to commit their crime.
I'm also doing jack shit to actually protect Nostr though. Maybe I do deserve criticism for not trying to introduce a new NIP, or create a fork of a Nostr client in order to implement a better image hosting solution. What do you think?
