Terrorists on myspace?

So I came across this page on myspace today. It appears to either be run by or for a group of islamic militants. There are tons of videos and pictures which show the same group of people in camo with guns and equipment. I don't know what to make of it, but is it something that should be brought to attention? Check it out.
