OpenStreetMap
I ran across that page today. It looks like some people don't care. They just merge nodes everywhere in the U.S. linking all together roads, rivers, power lines and admin boundaries.
In doing so they do not "Respect the work of others" who take time to properly fix the duplicates. They even make their work worse: those nodes that were duplicates on a road and a river could have been easily spotted using the duplicates map and converted to a bridge or a ford. Now it is wrong and hard to detect.
They did not "Discuss their plans" or if they did they did not follow advice as I have read warnings about the fact that there are a lot of errors resulting in mass-merging duplicate nodes (at http://matt.dev.openstreetmap.org/dupe_nodes/about.html to begin with).
They do not "Execute their plans with caution". I come across wrongly linked ways pretty much daily now.

The code of conduct was written in response to slap-happy imports in the USA, especially TIGER, much of wich deserves little respect. Repairing the broken topology form these imports justifies the odd bit of collateral damage, although you should still fix it when you find it.

As I read it, Nakor complains about automated edits that don't follow the code of conduct. And I agree the the kind of "collateral damage" that he describes is unacceptable. A bot connecting roads with powerlines and similar nonsense is in no way better than the results of the TIGER imports.

Yeah, I believe the problem is now people are fixing the duplicate nodes automatically. While some of them should be joined close to 100% of the time (edges of TIGER counties being one of them) others (such as NHD and TIGER nodes being coincident) obviously shouldn't.
Nakor, you should contact whoever is doing this and ask them to stop, if not take it to the mailing lists. There are sanctions available such as blocks to make people running bots pause and reconsider.

It would be worthwhile asking Keep Right or one of the other validators to identify nodes common to roads and power lines and other aftereffects of excessive node merging.

I contacted a few that I spotted with no response to date but no more problematic edits as well.
I had a couple ideas to submit to Keep Right which is really a great tool and I will just have another one to add. Thanks for the idea.
