What's wrong with being a hoarder anyway? So what if you have piles of crap half-way to the ceiling and little gunnels in amongst it so you can get from one room to the other? Your house, your life, your choice.
You are not conforming to societal norms! Oh no! Does anyone really give a shit? And if they do are they not the one with the problem?
Worst case I ever saw was at the house of a friend's mother on the south coast. You got a taste for what was to come in the entrance hall. This had been lined with crudely made bookshelves from floor to ceiling which held VHS tapes of what, at the time, was pretty much every Dr Who episode ever. Rooms were piled with crap, mainly old newspapers and magazines, to about 5 feet in height. The only place you could move about a bit was in the kitchen and the cellar. None of this bothered me, the deal breaker for me was that they had a baby and it had crapped everywhere and they had not cleaned it up. Now that was nasty.
