> the abundance of blocking in the 'verse in lieu of adequate spam controls, which ActivityPub fundamentally lacks

Bring your own algorithm can tackle spam (like adblocks). ActivityPub is flexible enough for Mastodon to build up references to algo-providers.

I've been frustrated by Mastodons slow movement on this, I considered approaching the popular clients to implement this. After all, ad-blockers run entirely on the client. A basic standard can be drawn up that governs how to boost or penalize toots' visibility based on keywords, author or instance, based on an updated list is viable today amd can run entirely on the user's device. Web-based clients are more complex, and require patching the standard Masto server or running in a sidecar.
