After having my personal image used by a particular, mentally disturbed, world-traveller I am a bit hyper sensitive to this sort of thing. I don't like people taking what isn't theirs without having the common decency to ask. I used to punish it, in the real world, quite severely. That's behind my stance on plagiarism on Hive. It's ingrained.

I'm not a lawyer so don't know all the intricacies.
