I reread your first comment and I think I just misread it the first time. (And you may have misread mine). I think we were just talking past each other.

We seem to agree on the important bits, namely that:

• "Creepiness" is defined and measured by the "creeped out" response of recipients.
• Therefore it depends not just on the action, but on the recipient and on how they perceive the actor.
• Therefore an action is not definitely creepy or noncreepy until carried out; it is hard to predict reactions.
• To the extent that the same action is perceived as creepy or not coming from different people, we shouldn't be talking about the action itself sometimes being creepy, but about the relevant differences between people.
