> If these are the kinds of people who are attracted to nostr

I think it's more that these people are around on every platform; but most platforms create (simple, vote-based; or complex, engagement-based) algorithmic filter-bubbles, so that you can live in blissful ignorance of these people's very persistent attempts to get your attention.

(A good example of an already-established platform that doesn't have this kind of filter, is Discord. If you join Discord servers at random, you'll often get flooded by DMs from bots trying to shove this same kind of content in your face.)

As much as the engagement-based recommender algorithms of sites like Twitter encourage "hate-following" and "doom-scrolling", they do have the nice property of inherently filtering out this kind of spam: these "human spambots" post things that can be predicted by their content to receive literally no engagement at all (since everything similar anyone's posted recently received no engagement at all); and so these spam posts get dropped out of any feed they'd otherwise appear in.

Nostr inherently cannot have any kind of online self-tuning algorithmic filter-bubble like this; such algorithms are powered by a global corpus of "everything everyone is currently posting, and every way that everyone else is reacting to it." Nostr relays only see the "notes" that are passing through them; and they have no idea what downstream Nostr clients think of those posts. So even if someone wanted to build a "smart relay" that does algorithmic filtering, there's no signal to power it.
