I think I remember it being said it's subjective and case by case.

Like, the painting of Venus or a statue of David would be "artistic", but a graphic image of a busty woman enjoying a cucumber a little too much would be "excessively explicit". Anything in between is a grey area, so probably best to err on the side of caution. On specific wikis, I'd check their list of rules and/or directly ask their admins.
