I don't know if this is real or a prank, but it claims to be a man cut in half by a horrific accident, ...and lives.

Looks legit. This happened in Cambodia (they are speaking Khmar) and no one is assisting him (typical of Cambodians as they are typically afraid to assist in accidents due to the possibility of being blamed for it).
The lack of blood could be for several reasons, although there is a large amount under the torso and around the legs. Malnourished (common in third world countries) would be my best guess as to why there's not a ton of blood, he also appears to be about a 55 kilo man so he's not going to have a large amount of blood like a fat westerner would. He's still alive because he's in shock and of course died later, but it's not uncommon for that to happen. When I was living in Thailand I saw several horrific accidents involving motorbikes, one which was burned into my mind forever which involved a pregnant woman who was thrown under a cement truck off her motorbike and the back wheel ran over her body tearing her abdomen open, the baby came out partially and died instantly along with the mother.
I"m saying this is legit for the reasons above, and mainly because I know the area and know that these types of accidents are very common throughout south east Asia. The most common form of transportation is motorbike (small 110cc-125cc scooters) and the amount of people killed on those things is quite staggering. Drunk westerners visiting the region are often victims of their own stupidity and you can find some really nasty videos of guys who were doing stupid shit on motorbikes in Thailand and what not, not my cup of tea, but you know.
I don't know if I want to view the other videos as I'm not really into viewing that kind of material, it effects me deeply and it's difficult for me to watch.
