Bruno, that was a great little post, and you're right.
If you look at the horrible history of Ilsa - She Wolf of the SS you'd discover how right you are. Anyone involved, who had sense, took their names off the credits to erase their involvement - some even had Holocaust survivor relatives! I guess, while making it, they divorced exploitation cinema from history, then found they couldn't. Those who didn't, including Dyanne Thorne, had a Jade-like reaction to face, and career oblivion. Thorne starred in the sequals Ilsa - Harem Keeper of the Oil Sheiks and Ilsa - Tigress of Siberia and other dumb and disgusting films and that was it. She was a fairly intelligent, and very striking, woman, nonetheless.
South America was the most insane for exploitation. Is this something to do with fascism again? For example, Bare Behind Bars, banned everywhere, was not only not banned in South America, they added extra hardcore porn inserts in case it wasn't extreme or vile enough.
A lot of these films are more silly and weird than extreme, however, like, for example, Sadomania which, apart from the dog-shagging-a-chained-up-lesbian scene, is just silly and weird. (Ajita Wilson just adds to this. S/he's pretty insane and great all round.)
Or maybe I've really dropped off the edge.
