You know what is funny about that? All of my NOSTR clients block this crap! Only one actually gives my notice and I've since shut out notifications. I've even blocked this NOSTR handle, yet it still can see me and if it is not blocked by others will continue it's campaigns.

So, yes, it's spam, annoying, and even if I block it, some relay will still route it.

Maybe I need to see what relays it is using and remove them.
