"Pornographic" is only one of the many meanings of the word "obscene". Taken from 

ob·scene  (b-sn, b-)adj.
 Offensive to accepted standards of decency or modesty.
 Inciting lustful feelings; lewd.
 Repulsive; disgusting: "The way he writes about the disease that killed her is simply obscene" (Michael Korda).
 So large in amount as to be objectionable or outrageous: "local merchants in nearby stores get hammered by stratospheric rents and obscene taxes" (Joe Queenan).
offensive or outrageous to accepted standards of decency or modesty
 (Law) Law (of publications) having a tendency to deprave or corrupt
 disgusting; repellent an obscene massacre
 offensive to morality or decency; indecent: obscene language.

As you can see, to limit "obscene messages" to simply "pornographic imagery" is clearly original research. And if I where you, I'd stop with the finger pointing accusations. This is Wikipedia, not a kindergarten. (Talk • Contribs)
