Well, yes, but I'm using "targeted" in the context of "personally targeted". Group targeting is less of a problem because then they are working on averages and predominant group characteristics, which does not mean any one individual does correspond to those. For example, a billboard may target an area with a message mainly meant for LGBT people, or for Hispanic people, but living or frequenting that area foes not mean you are LGBT or Hispanic respectively. There is still a level of anonymity there that protects privacy. I've updated my original comment to make this more clear, so thanks for calling out the ambiguity.
