People knock the guy but he is not blackmailing anyone to go on his show. They proactively apply to. They know exactly what they are letting themselves in for. It has been on air for 6 years.
I hardly think that we can take the fact that vulnerable and grossly uneducated people participate freely in something as an indication that it is benign. Not that that has any bearing on the man's condition, but I just had to respond to your defence of his show.
