Encrypted spam only affects the receiver, who can easily mark as spam just like any other DM.

it also clutters the server (relay). disk space is a scarce resource as much as attention is.

Nostr right now is a small close-knit community like early 90's Usenet. We need to be prepared for an eternal September.

You can have a deal with your users to delete GiftWraps after some time to declutter. But that is between the replay operator and the user. The same clutter can happen with DMs. So this is not an issue of the new method.

Relay monoliths that we have today will never scale to where we are going. None of today's architecture will survive.

I don't think spam would know how to find you? Even a friend needs a unique invite to connect with you. They have no way of finding you, or knowing who/where you are on SimpleX.
