Hi Will, 

Fully agree with you. I also tried to contribute to that changeset
discussion. If you hadn't reverted that admin level change, I would
have... 

Some of his ideas are on his diary pages [1] and my admin boundary page
[2].

To me this seems problematic because my understanding is that these are legal entities which either exist or they don't. Additionally, it makes OSM boundary data harder to use. If I run a query to find which boundaries a node is within, I'd only expect real admin boundary areas to be returned. The user is adding designation tags (designation=non-civil_parish) to indicate they aren't real, but this is undocumented and data users shouldn't have to check a secondary tag to find out whether a relation is a real civil parish or not.

I accept my initial comment suggesting that one of these relations should be deleted could have been worded much more tactfully, but I don't feel in justifies his aggressive responses since. I was frustrated at finding one of the these non-existent boundaries covering my local area with an inaccurate name.

This feels to me like an inappropriate use of "ref" and also redundant as the area can be calculated simply from the geometry anyway. When I queried this with the mapper (user alexkemp) via a changeset discussion [1] I got the following response:
