Client-side curation sounds like whitelisting effectively, if you follow only the curated feed and the curated feed resigns all events posted by selected keys, that’s a whitelist and seems like a decent solution for casual users so long as they can find trusted curators and clients that enable them to be easily discovered and subscribed to. What client is best for this currently?

On the flipside, if those “curators” were able to export and import lists of keys to automatically exclude from feeds, that would be very useful for the curators who have to manually or automatically sort events and new users to build their feeds. Is that feature currently available? Eliminating known bot accounts from feeds seems like minimum viable feature set for new curators in the current state of play.
