We need finer grained controls than what are provided today by #mastodon for #blocklists

For instance, what if the tooling allowed individuals or instances to say:

* "Only allow direct messages from this instance from people who are followed or where there is explicit consent to receive a direct message"

* "Automatically hide all content (under something like what's called a CW today) from this server unless there's explicit permission to show it from the user"

* "Block replies to this post"
