Hmm, not sure about this. Restricting profiles could make it harder for new users and might even create a FOMO effect for bad actors. A spam assassin-style approach seems better as a baseline. I use Ditto regularly to make 'good' profiles, and if that gets blocked, newer versions will be trickier for me to use. https://en.wikipedia.org/wiki/Apache_SpamAssassin
I've already implemented something like this with #Nosflare but do allow kind 0 events. However, that's only one piece of the anti-spam measures with Nosflare. By default, Nosflare requires a valid NIP-05 and optionally it can hash content and not allow duplicates. A new user can save their profile metadata to include a valid NIP-05 and all future events will be allowed. The bots haven't started using valid NIP-05 yet. So far, it has been working beautifully to stop the spam.
