If you believe the faintest in scientific principles all horoscopes are fakes.
Why should this be different?
It declares its self as fake. While others deny that charge.
These horoscopes are actually faked by you, sent to your friends anonymously. That's the difference...
what's crazy is giving out your friend's cellphone number to a service that fails to mention how they might use that number in the future. Here's a potential horoscope for you: "I see SMS spam in your future." :-)
