Yes but this is not a solution. Blocking a stalker in one client doesn't block a stalker in other clients.

I agree. Privacy is quite an issue on NOSTR.
But hey, it's a part of the Internet and I hope we all agree some things aren't meat to be posted on the internet.

You can have 100 stalkers and they can't do shit if you are privacy focused before a person interact with nostr. 

Maybe someday nostr will be fully anonymous. We'll see.
