I should be clear that my #personalopinion is that any user or server should be able to subscribe to #blocklists and #allowlists, built into the APIs. Servers should be able to run allow-only or block-only.

These features should be required for product entry in this space.

#blocklist #blocklistsubscription

@aral interesting perspective. I wonder if, perhaps, the answer could be the mid-size instances. Popular enough to demand federation with the big instances, small and plentiful enough to thwart #allowlists.
