This has to be some kind of brilliant hoax: a Twitter 'attribution troll' is showering threats on anyone who tweets a popular one-line poem.
On Press Inc., supposedly a division of Knopf Publishing (according to its Twitter profiles), was running a search of its own and issuing tweet after threatening tweet to anyone who dared publish a short (really short -- under 140 characters) poem by reclusive poet, Shaun Shane, without attribution. The entire poem reads as follows: "If only our tongues were made of glass, how much more careful we would be when we speak."
The threats--which have apparently escalated to imaginary police investigations over Amazon reviews, too--are baseless, writes TechDirt's Tim Cushing. Even if a tweet-length poem meets the expressive requirements for copyright protection, experts say it's unlikely to generate a credible lawsuit.
