I think that the 19 year old should be put in prision for the rest of his life. The child shouldn't be allowed on the internet unattended, and her myspace account should be deleted. As for myspace.com, it shouldn't be sued, but shut down. There have been so many cases like this, and you really don't know who's watching your profile.
I also use myspace, but it's only for chicks and friends. I can live easily without it, and all of my pictures are just my head and my shoulders. I do worry about my sister, because her pictures are worse than mine.
Really myspace shouldn't even be on the net, because it's just too much of a risk for teenagers. Myspace goers get younger every day, and these people are usually more nieve (sp???) than the older ones.
