I don't see this as very important. Anyone can buy a domain and point their NIP5 to it. Someone can buy a variation of my name and do this. Most domain registration information is hidden from the public. Using a domain provides no greater security or verification. Anyone can change their NIP5 nearly instantaneously. I'm currently sitting at nostr:nprofile1qqsyv47lazt9h6ycp2fsw270khje5egjgsrdkrupjg27u796g7f5k0spzemhxue69uhk2er9dchxummnw3ezumrpdejz7qgwwaehxw309ahx7uewd3hkctcprdmhxue69uhkummnw3ez6vfwde3x7tnpdenkzmnf9e3k75xqss4 while I wait for nostr:nprofile1qqsw5t3us9xs3gmclzjm37hvk2yy6pv9t96utjjttsj794hexc5x79qppemhxue69uhkummn9ekx7mp0qrmlyn to update BTCPayserver. Once that update hits, I'll self-host again. No one will notice. It may help if you use your domain for other uses, giving it more validity, but even that can be copied and duped. In my opinion, NIP5 is just an easy way to find your account rather than using an npub. Nothing more, nothing less. It's the WoT, not the NIP5, that helps me know which accounts are legit and which are scams. nostr:nevent1qqsd8jdhspa5jdl2wqeygdvxwx6yyr378xe5phhmlthd8l2pwqlj7kcpz4mhxue69uhkummnw3ezummcw3ezuer9wchsygppksv3qtdgls96jpyy4mynf064k74u7a0wmvu3yn5dwhjfraq6tcpsgqqqqqqsml9zg6
