I'd say the second one needs a "Warning: Violent" as well. My brother showed me that one a couple of years ago. Crazy stuff. You can literally see the chunks of the person fly around the field.
EDIT: Are you sure you didn't get your links mixed up havoc lol. The one you have marked as 'violent' is the one where they are watching the people having sex........although I guess their sex DOES look rather violent
