Cory Doctorow:
David sez, "a Mac program called Display Eater that has been set up by its developer to respond to the use of pirated CD keys by 'erasing something' -- apparently this is, in some instances, the home directory of the infringing Mac. Response over on Versiontracker, amongst other places, has been rather irate -- the PR disaster has already occurred"

(Thanks, David!)

Update: Jason sez, "Display Eater's developer posted a public letter on his website saying that it was all a hoax. Also, this isn't new to the Mac community. A similar incident occurred in 2004."
