“I’ve decided to adopt your old slogan with some minor tweaks. Kick rocks!”

I wish it was true, but there are ways to be evil on nostr as well.
I am new here, what are some examples of evil that have happened?
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.
Is there a good video that you’d recommend on how to use NOSTR the most sovereignly?
