If Jin wasn't a rapper, I'm still sure he would've done something.
But since he IS a rapper, and he has been signed, etc., his voice is better heard than most others. Especially when he's dissing an urban radio station.
Sure, there's always publicity involved with celebs, I totally agree with you, but IMO it seems you're trolling (directed at jobber). This thread is about Hot 97 mocking Tsunami victims and Jin dissing them, no point in bringing up what you did.
