Keeping posts by {{ preview.authors.join(', ') }}.
Nothing to remove: every post with a known poster is by someone on the list.
{{ preview.posts }} post(s), {{ preview.images }} image(s) found only on them, {{ preview.attachments }} attachment(s).
{{ preview.drops }} grouped post(s) that include them are ungrouped; the rest regroup on the next sweep.
Images that also belong to a kept post stay. If a name you want to keep appears above, add it to the source's "Only posts by" list first.
{{ preview.unknown_posts }} older post(s) don't record who posted them and are left alone.
