re those 'shows'.
Those who can afford it and need that sort of help pay for the help, no cameras involved.
Those with a sudden time line to get the issue fixed or else, the ones more likely to have the most severe issues, might apply to those shows, allow them to edit it any way they (program makers) chose, decide whatever they chose to throw away, making sure to edit in the 'juicy' bits.
Like some of the reality tv shows do, choose one to play the villain, to edit them to be a scapegoat and make a mockery of them by cunning editing, and the person only finds out after it is broadcast that they are publicly humiliated with dispersions cast about their character, but that is a whole different story.
Back to the the hoarder shows - have you ever seen 'after' reports from the person who called out for help?
One was left with only the clothes she had on at the time. She had certainly previously had been wearing more of her clothing than those few things, or that nothing else in the house could be saved.
Many of the complaining participants seem to say they have bigger problems 'after' than what they had before, and a far greater problem with trust.
And yes there may or may not have been a way to save the house. Probably they (producers and the residents) had a clue as to the house's viability before but the show required the big reveal at its dramatic end.
So no - not really a fan. Ritual humiliation is not something I enjoy watching, but then again, its why I don't like a lot of 'popular' tv shows that play on people being 'different or 'freaks' to be laughed at, but that is another story too.
Try 'Hidden Treasures" - its a book. I forget if its the one for the sufferer, or the family of the sufferer.
I've heard of people who found it helpful.
Forums for hoarders can give you some clues as well.
