“We will reject Apps for any content or behavior that we believe is over the line. What line, you ask? Well, as a Supreme Court Justice once said, ‘I’ll know it when I see it.’ And we think that you will also know it when you cross it,’’ the guidelines say.
Apple also says it will block applications that don’t do “something useful or provide some lasting entertainment.’’
“We don’t need any more Fart apps,’’ the guidelines said, referring to prank programs that let off noise.
