   database row expires. Upstream matched the two by exact end time, which never matched for one
   given in game (the database stores the time to the second), so it lasted until the player
   reconnected. A penalty marked passed also stops applying at once, not on the next 61-second tick.
+- Targeting by part of a name: when several names contain it, one that is exactly it (any case)
+  is picked, and otherwise the reply lists the matches. `css_ungag`, `css_unmute` and
+  `css_unsilence` match online players by part of the name too (upstream needed the full name),
+  falling back to the offline search only when no one online matches.
