Not all actions which are labeled creepy have negative consequences or are exclusive to creepy people. If someone does an action without negative consequences but that action is then labeled creepy prematurely without considering the motive behind it, then this premature labeling will have negative consequences. Bad labels mean bad models of reality which result in bad decisions. Mistaking someone for a creep when they're not precludes making friends with a potentially good person, and means your predictions of their behavior will be wrong.

You say that "they are failing to take steps to change this even when the negative consequences are pointed out to them". I am confused. You seem to be envisioning a very specific type of scenario here, and I don't know why you think that I would be envisioning the same scenario. Since when did my argument get restricted to instances where someone has been confronted with their creepiness and refused to change? My argument is meant to encourage caution in the people here are considering experiences from their own lives and trying to determine who is and isn't creepy, on a general overall sort of level, not to this very specific kind of instance that you mention.
