The persona's notification policy, and what it filtered

Settings has a Notifications section, also at /notifications/filtered: what notifications from people the persona does
not follow, people who do not follow it, new accounts, private mentions it did not ask for and limited accounts become
(accept, filter, drop), and the filtered ones, one request per account, let in (with that account from then on) or
dismissed. The Notifications tab says when requests wait. e2e: a stranger's like waits in a request reached from the
tab and comes back once let in; the policy and the stranger's permission are put back afterwards (Pasture.Mongo).
