A wordpress blog of mine has that post format, but on the end of every url it has added a /trackback/. So dupe content ahoy!.
Wordpress is a nightmare for these auto generated pages, you really need your head screwed on to not get caught out.
Additionally if you turn off trackbacks it just turns them into 302`s meaning temporary. Trackback.php needs editing to change it to 301.
