I think the surmise in your last paragraph is basically correct. I have no idea if there was any stalking going on. My calendar is public within the company like everyone else, but I definitely wouldn't feel comfortable if I found that an enemy were using that information to harass or intimidate me, and I would expect management to deal with that severely. This goes twice for engineers stalking HR people, since generally the HR folks have much less power and influence in the organization.
