The editor in question is strongly suspected to be Wikipedia:Long-term abuse/Cause of death vandal. A link like CBE is piped through a redirect because if you hover over that link, it shows the full title; and when you click on it, you get the "(Redirected from Commander of the Most Excellent Order of the British Empire)" message at the top of the page. It's also a WP:NOTBROKEN situation - one day, we might split out the five different levels into their own articles. The article must not be moved, since it covers seven awards -
Member of the Most Excellent Order of the British Empire (MBE)
Officer of the Most Excellent Order of the British Empire (OBE)
Commander of the Most Excellent Order of the British Empire (CBE)
Dame Commander of the Most Excellent Order of the British Empire (DBE)
Knight Commander of the Most Excellent Order of the British Empire (KBE)
Dame Grand Cross of the Most Excellent Order of the British Empire (GBE)
Knight Grand Cross of the Most Excellent Order of the British Empire (GBE)
that is, five different levels, two having gender-specific titles (as I mentioned before, a lot of people think that "OBE" stands for "Order of the British Empire" - it doesn't, since the O stands for Officer).
