It does sound very clever, I guess
"One Indian cyber expert, Ravi V. Prasad, says, "Such groups use porn sites because it would be the last place someone would expect Islamic fundamentalists." The second favourite are sports sites. Again, this runs against the Taliban grain and the large volumes of site visitors provide good cover."
It kinda reminds me of the Sep. 11th terrorists enjoying their last week on earth by going out and partying with hookers. I guess it's okay to bend the moral code of conduct in the name of "the cause".
