https://who.is/whois/netim.com is the name of the registrar for the domain, and i see that https://who.is/whois/dnsnode.net is who owns that

idk what to say, only goes 2 levels deep and you can find a physical address

i'm not doxxing anyone, but this asshat twice, at least, has spammed me with disgusting animated and still image links and intensively tried psychological intimidation on me tonight so let's just say you can find out where they register their domains and how they are making nostr clients that they don't seem that keen to broadly advertise
