When a sysop revision deletes one or more revision(s) or log(s), they are returned to that same Special:RevisionDelete page with the log of their action(s) and a green message indicating success.
When (un)suppressing an AbuseFilter entry, however, an oversighter are returned to the entire generic Special:AbuseLog with no feedback or acknowledgement to the user that the entry was successfully (un)suppressed; the oversighter must use the back button in their browser to confirm success.
