I can't help but feel the people doing this are really lighting a huge signal fire to say they are deeply troubled by something and need/want help. Several of the Utubers I saw seemed to be afraid/sad/unnatural when they make their denials.
Besides, what a ridiculous concept - selling a soul.
If you believe there is no such thing as a soul, then all you do here is get a free DVD for doing basically nothing
If you do believe you have a soul, how do you come to the conclusion it is only worth a piece of plastic?
If you do believe you have a soul, why would you think that it is yours to sell or that someone else could take it?
I think this site may cause more people to think about the brevity of this life. Should we thank these folks for their good work?
