Although I strive for kindness in all things, I do make pre-emptive moves to protect my works. But in the cyber world such protections as copyright registration seem to carry little weight. A friend sent me a link to a Wiki article about "book curses," used in long-ago times when each book was hand-made and was considered a precious object in and of itself- not just for the knowledge it contained (precious enough on its own merit.) These curses were written into the books by the scribes and called down the wrath of God upon book thieves and even book "borrowers" who neglect to return the volume.
Perhaps it is time to update the "book curse." So, here is a modern version:
"For him that stealeth this image from its owner, let it change into a serpent in his hand and rend him. Let him be struck with palsy, and all his members blasted. Let him languish in pain crying out for mercy, & let there be no surcease to his agony till he sing in dissolution. Let computerworms gnaw his entrails ... when at last he goeth to his final punishment, let the flames of Hell consume him forever."
