Would i get in any kind of trouble if i downloaded music or movies from limewire? Besides that, why is that ilegal, i thought that it was ok as long as it wasnt done to make profit out of it or changing it, also, its not like im making copies of it.

Also, hypotetically , lets say i dowloaded teen porn, not child, by teen i mean girls between 16-17, would i have problems if i did that even though im under 18?
