Here is a great example why NIP-05 matters for verification. Without it, there are no way for someone to verify which account is correct or not. This bot is replicated to tag a lot of users.



Yes, the fake account can always use another valid NIP-05, but that is equal to someone attempting to trick you into going to "micr0soft" website.

Nostria has a spam filter for post where hundreds of accounts is tagged, if you're an existing user it will be set to unlimited. New default is 100. If you're already using Nostria, check it out in settings and set it to your preferred limit.
