I am new here, what are some examples of evil that have happened?

If you design an app that uses nostr but doesn't allow people to set their own relays, tracks users and have ads... that is practically the same as Google.

#darknostr

Core people pretending they're not shitcoiners

We have had clients that send nsecs to their servers, relays tracking user locations, media servers tracking locations, clients that don't let user setup their own relays, clients that only want to do their own formats for things, etc etc etc.
