Since then, Alexander Griffioen (SHRTURL's creator) has announced that he's shutting it down.
Griffioen says he was unnerved by people using his lie-generating tool to generate lies that he thought were vicious -- like, for instance, a death rumor about Formula One racer Michael Schumacher. If you've been on the internet say, twice, it's not incredibly surprising that people would use a hoax tool to spread death hoaxes.
Griffioen also says that he'll sell the site to anyone who makes him a good enough offer.
Anyway, life is short, and I'm not sure I want to spend much time being outraged by someone trying to profit off of internet lies. Or being baldly disingenuous. But the upshot of all this is that there's one less hoax factory in production, at least for now.
