There is slightly more insight in a comment under the YouTube in which a family member states that direct kin have endeavoured to declutter but became overwhelmed by it. Whilst there is no comment about the condition at present, there is that the gentleman requires 'professional help'. This is what I summarised a number of posts back. It is, it would appear, a failing in social services, rather than the landlord in the first instance. My guess would be, as is all too common in such cases, that DBC will have endeavoured to get that support but got nowhere.
