Japanese game studio 0verflow is populated by geniuses. Rather than combat piracy with oppressive DRM, the developers of erotic title Cross Days is tackling the thieves in a more direct way -- wielding abject humiliation as its weapon.
A fake trojan has been released online, hiding within a fake installer for Cross Days. Once installed, the trojan will then gather data from the pirate's computer and poses a fake survey for the player to fill out. Once the survey is done and the program is finished gathering data, everything is posted to a public Web site, alongside a screenshot of the "victim's" desktop.
If the pirate wants his or her information taken down from the site, they need to click a button admitting they stole Cross Days and apologize for the naughty thing they did. If you think 0verflow can't do this, think again -- it's all covered in the program's Terms of Service, which none of us read, but probably should.
So there you are. Be very careful about what you try to pilfer. Playing something like Cross Days is embarrassing enough without telling the world about it, some would say.
