I think we're digressing here a little, but what I mean is gathering a large amount of personal data specific to one person, including an itinerary of travel and whereabouts for the coming week (for example) for lulz does not compute as you would have thought there is some agenda behind it all. I'd be more worried that someone was gathering such images and information about me than by someone writing the words "I'm going to bathe in their blood" next to a single image of me that could have been mined from google or facebook by someone who doesn't know me. I don't really know anything about libel laws, but what you've done again is to describe an offence (e.g. harrassment) and infer that by saying that shouldn't happen is a violation of freedom of speech. Saying whatever you want doesn't harm anyone. Mounting a campaign designed to intimidate/harrass someone might.
