Why does it make you nervous? Do you really care about any of those people's lives? Do you really think any of it is real? All those idiots went on there knowing exactly what would happen.
Cause, for example, one idiot has a “new girlfriend” but hasn’t broken it off with the one he brought. Plus, they show video clips to the “other” that are snapshots and leave a lot of questions. And yes, it is VERY real.
It's all scripted and they know in advance who is going to do what. Whatever videos you think you're seeing are total acting. I love me some ID channel.
