R6 moderation in decePub: users and personas, accounts, report actions, deletions, suspended personas

Administration's Users & personas (administrators): logins searched and opened into their personas and groups; roles,
bans, two-factor reset and deletion of a login; silence, suspension and deletion of a persona; a group deleted. Accounts
(moderators): local personas and remote accounts searched or listed as moderated, silenced and suspended with a staff
note and a warning. Reports resolve with an action. ActDialog asks for the note, the warning or the password and is the
act's confirmation. A login deletes its own persona and the groups it owns with its password. Suspended personas can't
be chosen; one refused a token mid-session moves the session to another, or to none, once. Warnings show in
notifications, limited accounts on their profile, and moderators remove a post from its card.
