Since when has "flogged" come to mean something other than "beaten (often) with a stick"? After doing a search, our freind Phranz (in another *life) seems to be the only one who has used it (here) as I've heard it recently as meaning "sold":

"...The only place where Welsh was flogged as a tourist concept was at Portmeirion, but we went there because of "The Prisoner", not because it was Welsh.

...yet, I could accept my original meaning in his context (which I'm sure I did at the time).

BTW - "Dr. Flog" is the famous Chicago area "Golf Rd." backwards (an in-car passenger game called "read the signs backwards" that we play on-occasion).
