Interestingly enough, I couldn't find your post in General Mapping.
It is a mess. Look at the History. Those are Maps Editors doing those edits. Could it get worse? Yes! Maps Listing Editors are leaking into my State. Both are Googlers so everything that they do goes through.
North Carolina apparently has acquired the same problem that's plagued South Carolina for a while. It's a Sandbox for new Googlers. I'm running into the same thing here
I don't usually go over the state line except around Charlotte but I was able to clear a few of your edits.
